A few subsystems are using the same define "NAMESIZE".  This has been
working so far because they define it to the same number.  However, I
want to change the size of eth_device's NAMESIZE, so rather than tweak
the define names, simply drop references to it.  Almost no one does,
and the handful that do can easily be changed to a sizeof().

Instead of counting the device index everytime a functions needs it, store
it in the eth_device struct. eth_register() keeps track of the indices and
updates the device's index number. This simplifies some functions in
net/eth.c.

Additionally, a network driver can now query its index, eg. to get the
correct environment ethaddr name.

When building u-boot as 64 bit application (e.g. sandbox) ulong might be
64 bits in size. This breaks network code as IPaddr_t is 64 bytes in
size then and an IPv4 address is 32 bits in size. This patch makes sure
that IPaddr_t is always 32 bits in size. Also some warnings introduced
by this patch are fixed.

ICMP packets can tell you when there is no server at the other end. It

Built-in Ethernet adapters support setting the mac address by means of a
ethaddr environment variable for each interface (ethaddr, eth1addr, eth2addr).

This adds similar support to the USB network side, using the names
usbethaddr, usbeth1addr, etc. They are kept separate since we don't want
a USB device taking the MAC address of a built-in device or vice versa.

There are boards out there that do not have network support in
U-Boot (CONFIG_CMD_NET not set), but they do so in Linux. This
makes it desirable to be able to port network configuration (like
the IP address) to the Linux kernel.

We should not make the passing of the IP configuration to Linux
dependent on U-Boot features / settings.

For this, make getenv_IPaddr() global. This fixes build error

u-boot/lib_xxx/board.c:360: undefined reference to `getenv_IPaddr'

on various architectures.

In the previous enetaddr refactoring, the assumption with commit 56b555a6
was that the eth layer would handle the env -> device enetaddr syncing.
This was not the case as eth_initialize() is called only once and the sync
occurs there.  So make sure the eth_init() function does the env -> device
sync with every network init.

Here it is again - slightly modified & smaller:
  - update to 2009-06 (Pieter's patch was for U-Boot 1.2.0)
  - README.dns is added
  - syntax is changed (now takes a third option, the env var to store
    the result in)
  - add a random port() function in net.c
  - sort Makefile in ./net/Makefile
  - dns just returns unless a env var is given
  - run through checkpatch, and clean up style issues
  - remove packet from stack
  - cleaned up some comments
  - failure returns much faster (if server responds, don't wait for
    timeout)
  - use built in functions (memcpy) rather than byte copy.

The purpose of this routine is receiving a single network frame, outside of
U-Boot's NetLoop(). Exporting it to standalone programs that run on top of
U-Boot will let them utilise networking facilities. For sending a raw frame
the already existing eth_send() can be used.

The direct consumer of this routine is the newly introduced API layer for
external applications (enabled with CONFIG_API).
