-INTRODUCTION
-
-lwIP is a small independent implementation of the TCP/IP protocol
-suite that has been developed by Adam Dunkels at the Computer and
-Networks Architectures (CNA) lab at the Swedish Institute of Computer
-Science (SICS).
-
-The focus of the lwIP TCP/IP implementation is to reduce the RAM usage
-while still having a full scale TCP. This making lwIP suitable for use
-in embedded systems with tens of kilobytes of free RAM and room for
-around 40 kilobytes of code ROM.
-
-
-FEATURES
-
-  * IP (Internet Protocol, IPv4 and IPv6) including packet forwarding over
-    multiple network interfaces
-  * ICMP (Internet Control Message Protocol) for network maintenance and debugging
-  * IGMP (Internet Group Management Protocol) for multicast traffic management
-  * MLD (Multicast listener discovery for IPv6). Aims to be compliant with 
-    RFC 2710. No support for MLDv2
-  * ND (Neighbor discovery and stateless address autoconfiguration for IPv6).
-    Aims to be compliant with RFC 4861 (Neighbor discovery) and RFC 4862
-    (Address autoconfiguration)
-  * UDP (User Datagram Protocol) including experimental UDP-lite extensions
-  * TCP (Transmission Control Protocol) with congestion control, RTT estimation
-    and fast recovery/fast retransmit
-  * raw/native API for enhanced performance
-  * Optional Berkeley-like socket API
-  * DNS (Domain names resolver)
-
-
-APPLICATIONS
-
-  * HTTP server with SSI and CGI
-  * SNMPv2c agent with MIB compiler (Simple Network Management Protocol)
-  * SNTP (Simple network time protocol)
-  * NetBIOS name service responder
-  * MDNS (Multicast DNS) responder
-  * iPerf server implementation

-DEVELOPMENT
-
-lwIP has grown into an excellent TCP/IP stack for embedded devices,
-and developers using the stack often submit bug fixes, improvements,
-and additions to the stack to further increase its usefulness.
-
-Development of lwIP is hosted on Savannah, a central point for
-software development, maintenance and distribution. Everyone can
-help improve lwIP by use of Savannah's interface, Git and the
-mailing list. A core team of developers will commit changes to the
-Git source tree.
-
-The lwIP TCP/IP stack is maintained in the 'lwip' Git module and
-contributions (such as platform ports) are in the 'contrib' Git module.
-
-See doc/savannah.txt for details on Git server access for users and
-developers.
-
-The current Git trees are web-browsable:
-  http://git.savannah.gnu.org/cgit/lwip.git
-  http://git.savannah.gnu.org/cgit/lwip/lwip-contrib.git
-
-Submit patches and bugs via the lwIP project page:
-  http://savannah.nongnu.org/projects/lwip/
-
-Continuous integration builds (GCC, clang):
-  https://travis-ci.org/yarrick/lwip-merged
-
-
-DOCUMENTATION
-
-Self documentation of the source code is regularly extracted from the current
-Git sources and is available from this web page:
-  http://www.nongnu.org/lwip/
-
-There is now a constantly growing wiki about lwIP at
-  http://lwip.wikia.com/wiki/LwIP_Wiki
-
-Also, there are mailing lists you can subscribe at
-  http://savannah.nongnu.org/mail/?group=lwip
-plus searchable archives:
-  http://lists.nongnu.org/archive/html/lwip-users/
-  http://lists.nongnu.org/archive/html/lwip-devel/
-
-lwIP was originally written by Adam Dunkels:
-  http://dunkels.com/adam/
-
-Reading Adam's papers, the files in docs/, browsing the source code
-documentation and browsing the mailing list archives is a good way to
-become familiar with the design of lwIP.

components/net/lwip-2.0.0/UPGRADING

-This file lists major changes between release versions that require
-ports or applications to be changed. Use it to update a port or an
-application written for an older version of lwIP to correctly work
-with newer versions.
-
-
-(git master)
-
-  * [Enter new changes just after this line - do not remove this line]
-
-  * TODO
-
-(2.0.0)
-
-  ++ Application changes:
-
-  * Changed netif "up" flag handling to be an administrative flag (as opposed to the previous meaning of
-    "ip4-address-valid", a netif will now not be used for transmission if not up) -> even a DHCP netif
-    has to be set "up" before starting the DHCP client
-  * Added IPv6 support (dual-stack or IPv4/IPv6 only)
-  * Changed ip_addr_t to be a union in dual-stack mode (use ip4_addr_t where referring to IPv4 only).
-  * Major rewrite of SNMP (added MIB parser that creates code stubs for custom MIBs);
-    supports SNMPv2c (experimental v3 support)
-  * Moved some core applications from contrib repository to src/apps (and include/lwip/apps)
-
-  +++ Raw API:
-    * Changed TCP listen backlog: removed tcp_accepted(), added the function pair tcp_backlog_delayed()/
-      tcp_backlog_accepted() to explicitly delay backlog handling on a connection pcb
-
-  +++ Socket API:
-    * Added an implementation for posix sendmsg()
-    * Added LWIP_FIONREAD_LINUXMODE that makes ioctl/FIONREAD return the size of the next pending datagram
-
-  ++ Port changes
-
-  +++ new files:
-    * MANY new and moved files! 
-    * Added src/Filelists.mk for use in Makefile projects
-    * Continued moving stack-internal parts from abc.h to abc_priv.h in sub-folder "priv"
-      to let abc.h only contain the actual application programmer's API
-
-  +++ sys layer:
-    * Made LWIP_TCPIP_CORE_LOCKING==1 the default as it usually performs better than
-      the traditional message passing (although with LWIP_COMPAT_MUTEX you are still
-      open to priority inversion, so this is not recommended any more)
-    * Added LWIP_NETCONN_SEM_PER_THREAD to use one "op_completed" semaphore per thread
-      instead of using one per netconn (these semaphores are used even with core locking
-      enabled as some longer lasting functions like big writes still need to delay)
-    * Added generalized abstraction for itoa(), strnicmp(), stricmp() and strnstr()
-      in def.h (to be overridden in cc.h) instead of config 
-      options for netbiosns, httpd, dns, etc. ...
-    * New abstraction for hton* and ntoh* functions in def.h.
-      To override them, use the following in cc.h: 
-      #define lwip_htons(x) <your_htons>
-      #define lwip_htonl(x) <your_htonl>
-
-  +++ new options:
-     * TODO
-
-  +++ new pools:
-     * Added LWIP_MEMPOOL_* (declare/init/alloc/free) to declare private memp pools
-       that share memp.c code but do not have to be made global via lwippools.h
-     * Added pools for IPv6, MPU_COMPATIBLE, dns-api, netif-api, etc.
-     * added hook LWIP_HOOK_MEMP_AVAILABLE() to get informed when a memp pool was empty and an item
-       is now available
-
-  * Signature of LWIP_HOOK_VLAN_SET macro was changed
-
-  * LWIP_DECLARE_MEMORY_ALIGNED() may be used to declare aligned memory buffers (mem/memp)
-    or to move buffers to dedicated memory using compiler attributes
-
-  * Standard C headers are used to define sized types and printf formatters
-    (disable by setting LWIP_NO_STDINT_H=1 or LWIP_NO_INTTYPES_H=1 if your compiler
-    does not support these)
-
-
-  ++ Major bugfixes/improvements
-
-  * Added IPv6 support (dual-stack or IPv4/IPv6 only)
-  * Major rewrite of PPP (incl. keep-up with apache pppd)
-    see doc/ppp.txt for an upgrading how-to
-  * Major rewrite of SNMP (incl. MIB parser)
-  * Fixed timing issues that might have lead to losing a DHCP lease
-  * Made rx processing path more robust against crafted errors
-  * TCP window scaling support
-  * modification of api modules to support FreeRTOS-MPU (don't pass stack-pointers to other threads)
-  * made DNS client more robust
-  * support PBUF_REF for RX packets
-  * LWIP_NETCONN_FULLDUPLEX allows netconn/sockets to be used for reading/writing from separate
-    threads each (needs LWIP_NETCONN_SEM_PER_THREAD)
-  * Moved and reordered stats (mainly memp/mib2)
-
-(1.4.0)
-
-  ++ Application changes:
-
-  * Replaced struct ip_addr by typedef ip_addr_t (struct ip_addr is kept for
-    compatibility to old applications, but will be removed in the future).
-
-  * Renamed mem_realloc() to mem_trim() to prevent confusion with realloc()
-
-  +++ Raw API:
-    * Changed the semantics of tcp_close() (since it was rather a
-      shutdown before): Now the application does *NOT* get any calls to the recv
-      callback (aside from NULL/closed) after calling tcp_close()
-
-    * When calling tcp_abort() from a raw API TCP callback function,
-      make sure you return ERR_ABRT to prevent accessing unallocated memory.
-      (ERR_ABRT now means the applicaiton has called tcp_abort!)
-
-  +++ Netconn API:
-    * Changed netconn_receive() and netconn_accept() to return
-      err_t, not a pointer to new data/netconn.
-
-  +++ Socket API:
-    * LWIP_SO_RCVTIMEO: when accept() or recv() time out, they
-      now set errno to EWOULDBLOCK/EAGAIN, not ETIMEDOUT.
-
-    * Added a minimal version of posix fctl() to have a
-      standardised way to set O_NONBLOCK for nonblocking sockets.
-
-  +++ all APIs:
-    * correctly implemented SO(F)_REUSEADDR
-
-  ++ Port changes
-
-  +++ new files:
-
-    * Added 4 new files: def.c, timers.c, timers.h, tcp_impl.h:
-
-    * Moved stack-internal parts of tcp.h to tcp_impl.h, tcp.h now only contains
-      the actual application programmer's API
-  
-    * Separated timer implementation from sys.h/.c, moved to timers.h/.c;
-      Added timer implementation for NO_SYS==1, set NO_SYS_NO_TIMERS==1 if you
-      still want to use your own timer implementation for NO_SYS==0 (as before).
-
-  +++ sys layer:
-
-    * Converted mbox- and semaphore-functions to take pointers to sys_mbox_t/
-      sys_sem_t;
-
-    * Converted sys_mbox_new/sys_sem_new to take pointers and return err_t;
-
-    * Added Mutex concept in sys_arch (define LWIP_COMPAT_MUTEX to let sys.h use
-      binary semaphores instead of mutexes - as before)
-
-  +++ new options:
-
-     * Don't waste memory when chaining segments, added option TCP_OVERSIZE to
-       prevent creating many small pbufs when calling tcp_write with many small
-       blocks of data. Instead, pbufs are allocated larger than needed and the
-       space is used for later calls to tcp_write.
-
-     * Added LWIP_NETIF_TX_SINGLE_PBUF to always copy to try to create single pbufs
-       in tcp_write/udp_send.
-
-    * Added an additional option LWIP_ETHERNET to support ethernet without ARP
-      (necessary for pure PPPoE)
-
-    * Add MEMP_SEPARATE_POOLS to place memory pools in separate arrays. This may
-      be used to place these pools into user-defined memory by using external
-      declaration.
-
-    * Added TCP_SNDQUEUELOWAT corresponding to TCP_SNDLOWAT
-
-  +++ new pools:
-
-     * Netdb uses a memp pool for allocating memory when getaddrinfo() is called,
-       so MEMP_NUM_NETDB has to be set accordingly.
-
-     * DNS_LOCAL_HOSTLIST_IS_DYNAMIC uses a memp pool instead of the heap, so
-       MEMP_NUM_LOCALHOSTLIST has to be set accordingly.
-
-     * Snmp-agent uses a memp pools instead of the heap, so MEMP_NUM_SNMP_* have
-       to be set accordingly.
-
-     * PPPoE uses a MEMP pool instead of the heap, so MEMP_NUM_PPPOE_INTERFACES
-       has to be set accordingly
-
-  * Integrated loopif into netif.c - loopif does not have to be created by the
-    port any more, just define LWIP_HAVE_LOOPIF to 1.
-
-  * Added define LWIP_RAND() for lwip-wide randomization (needs to be defined
-    in cc.h, e.g. used by igmp)
-
-  * Added printf-formatter X8_F to printf u8_t as hex
-
-  * The heap now may be moved to user-defined memory by defining
-    LWIP_RAM_HEAP_POINTER as a void pointer to that memory's address
-
-  * added autoip_set_struct() and dhcp_set_struct() to let autoip and dhcp work
-    with user-allocated structs instead of calling mem_malloc
-
-  * Added const char* name to mem- and memp-stats for easier debugging.
-
-  * Calculate the TCP/UDP checksum while copying to only fetch data once:
-    Define LWIP_CHKSUM_COPY to a memcpy-like function that returns the checksum
-
-  * Added SO_REUSE_RXTOALL to pass received UDP broadcast/multicast packets to
-    more than one pcb.
-
-  * Changed the semantics of ARP_QUEUEING==0: ARP_QUEUEING now cannot be turned
-    off any more, if this is set to 0, only one packet (the most recent one) is
-    queued (like demanded by RFC 1122).
-
-  
-  ++ Major bugfixes/improvements
-
-  * Implemented tcp_shutdown() to only shut down one end of a connection
-  * Implemented shutdown() at socket- and netconn-level
-  * Added errorset support to select() + improved select speed overhead
-  * Merged pppd to v2.3.11 (including some backported bugfixes from 2.4.x)
-  * Added timer implementation for NO_SYS==1 (may be disabled with NO_SYS_NO_TIMERS==1
-  * Use macros defined in ip_addr.h to work with IP addresses
-  * Implemented many nonblocking socket/netconn functions
-  * Fixed ARP input processing: only add a new entry if a request was directed as us
-  * mem_realloc() to mem_trim() to prevent confusion with realloc()
-  * Some improvements for AutoIP (don't route/forward link-local addresses, don't break
-    existing connections when assigning a routable address)
-  * Correctly handle remote side overrunning our rcv_wnd in ooseq case
-  * Removed packing from ip_addr_t, the packed version is now only used in protocol headers
-  * Corrected PBUF_POOL_BUFSIZE for ports where ETH_PAD_SIZE > 0
-  * Added support for static ARP table entries

-1 Introduction
-
-This document describes some guidelines for people participating
-in lwIP development.
-
-2 How to contribute to lwIP
-
-Here is a short list of suggestions to anybody working with lwIP and 
-trying to contribute bug reports, fixes, enhancements, platform ports etc.
-First of all as you may already know lwIP is a volunteer project so feedback
-to fixes or questions might often come late. Hopefully the bug and patch tracking 
-features of Savannah help us not lose users' input.
-
-2.1 Source code style:
-
-1. do not use tabs.
-2. indentation is two spaces per level (i.e. per tab).
-3. end debug messages with a trailing newline (\n).
-4. one space between keyword and opening bracket.
-5. no space between function and opening bracket.
-6. one space and no newline before opening curly braces of a block.
-7. closing curly brace on a single line.
-8. spaces surrounding assignment and comparisons.
-9. don't initialize static and/or global variables to zero, the compiler takes care of that.
-10. use current source code style as further reference.
-
-2.2 Source code documentation style:
-
-1. JavaDoc compliant and Doxygen compatible.
-2. Function documentation above functions in .c files, not .h files.
-   (This forces you to synchronize documentation and implementation.)
-3. Use current documentation style as further reference.
- 
-2.3 Bug reports and patches:
-
-1. Make sure you are reporting bugs or send patches against the latest
-   sources. (From the latest release and/or the current Git sources.)
-2. If you think you found a bug make sure it's not already filed in the
-   bugtracker at Savannah.
-3. If you have a fix put the patch on Savannah. If it is a patch that affects
-   both core and arch specific stuff please separate them so that the core can
-   be applied separately while leaving the other patch 'open'. The preferred way
-   is to NOT touch archs you can't test and let maintainers take care of them.
-   This is a good way to see if they are used at all - the same goes for unix
-   netifs except tapif.
-4. Do not file a bug and post a fix to it to the patch area. Either a bug report
-   or a patch will be enough.
-   If you correct an existing bug then attach the patch to the bug rather than creating a new entry in the patch area.
-5. Patches should be specific to a single change or to related changes. Do not mix bugfixes with spelling and other
-   trivial fixes unless the bugfix is trivial too. Do not reorganize code and rename identifiers in the same patch you
-   change behaviour if not necessary. A patch is easier to read and understand if it's to the point and short than
-   if it's not to the point and long :) so the chances for it to be applied are greater. 
-
-2.4 Platform porters:
-
-1. If you have ported lwIP to a platform (an OS, a uC/processor or a combination of these) and
-   you think it could benefit others[1] you might want discuss this on the mailing list. You
-   can also ask for Git access to submit and maintain your port in the contrib Git module.

-/**
- * @page pitfalls Common pitfalls
- *
- * Multiple Execution Contexts in lwIP code
- * ========================================
- *
- * The most common source of lwIP problems is to have multiple execution contexts
- * inside the lwIP code.
- * 
- * lwIP can be used in two basic modes: @ref lwip_nosys (no OS/RTOS 
- * running on target system) or @ref lwip_os (there is an OS running
- * on the target system).
- *
- * Mainloop Mode
- * -------------
- * In mainloop mode, only @ref callbackstyle_api can be used.
- * The user has two possibilities to ensure there is only one 
- * exection context at a time in lwIP:
- *
- * 1) Deliver RX ethernet packets directly in interrupt context to lwIP
- *    by calling netif->input directly in interrupt. This implies all lwIP 
- *    callback functions are called in IRQ context, which may cause further
- *    problems in application code: IRQ is blocked for a long time, multiple
- *    execution contexts in application code etc. When the application wants
- *    to call lwIP, it only needs to disable interrupts during the call.
- *    If timers are involved, even more locking code is needed to lock out
- *    timer IRQ and ethernet IRQ from each other, assuming these may be nested.
- *
- * 2) Run lwIP in a mainloop. There is example code here: @ref lwip_nosys.
- *    lwIP is _ONLY_ called from mainloop callstacks here. The ethernet IRQ
- *    has to put received telegrams into a queue which is polled in the
- *    mainloop. Ensure lwIP is _NEVER_ called from an interrupt, e.g.
- *    some SPI IRQ wants to forward data to udp_send() or tcp_write()!
- *
- * OS Mode
- * -------
- * In OS mode, @ref callbackstyle_api AND @ref sequential_api can be used.
- * @ref sequential_api are designed to be called from threads other than
- * the TCPIP thread, so there is nothing to consider here.
- * But @ref callbackstyle_api functions must _ONLY_ be called from
- * TCPIP thread. It is a common error to call these from other threads
- * or from IRQ contexts. ​Ethernet RX needs to deliver incoming packets
- * in the correct way by sending a message to TCPIP thread, this is
- * implemented in tcpip_input().​​
- * Again, ensure lwIP is _NEVER_ called from an interrupt, e.g.
- * some SPI IRQ wants to forward data to udp_send() or tcp_write()!
- * 
- * 1) tcpip_callback() can be used get called back from TCPIP thread,
- *    it is safe to call any @ref callbackstyle_api from there.
- *
- * 2) Use @ref LWIP_TCPIP_CORE_LOCKING. All @ref callbackstyle_api
- *    functions can be called when lwIP core lock is aquired, see
- *    @ref LOCK_TCPIP_CORE() and @ref UNLOCK_TCPIP_CORE().
- *    These macros cannot be used in an interrupt context!
- *    Note the OS must correctly handle priority inversion for this.

-/**
- * @defgroup lwip_nosys Mainloop mode ("NO_SYS")
- * @ingroup lwip
- * Use this mode if you do not run an OS on your system. \#define NO_SYS to 1.
- * Feed incoming packets to netif->input(pbuf, netif) function from mainloop,
- * *not* *from* *interrupt* *context*. You can allocate a @ref pbuf in interrupt
- * context and put them into a queue which is processed from mainloop.\n
- * Call sys_check_timeouts() periodically in the mainloop.\n
- * Porting: implement all functions in @ref sys_time and @ref sys_prot.\n
- * You can only use @ref callbackstyle_api in this mode.\n

-/**
- * @defgroup lwip_os OS mode (TCPIP thread)
- * @ingroup lwip
- * Use this mode if you run an OS on your system. It is recommended to
- * use an RTOS that correctly handles priority inversion and
- * to use @ref LWIP_TCPIP_CORE_LOCKING.\n
- * Porting: implement all functions in @ref sys_layer.\n
- * You can use @ref callbackstyle_api together with @ref tcpip_callback,
- * and all @ref sequential_api.

-This directory contains a script ('makefsdata') to create C code suitable for
-httpd for given html pages (or other files) in a directory.
-
-There is also a plain C console application doing the same and extended a bit.
-
-Usage: htmlgen [targetdir] [-s] [-i]s
-   targetdir: relative or absolute path to files to convert
-   switch -s: toggle processing of subdirectories (default is on)
-   switch -e: exclude HTTP header from file (header is created at runtime, default is on)
-   switch -11: include HTTP 1.1 header (1.0 is default)
-
-  if targetdir not specified, makefsdata will attempt to
-  process files in subdirectory 'fs'.
