As per RFC4821 7.3.  Selecting Probe Size, a probe timer should
be armed once probing has converged. Once this timer expired,
probing again to take advantage of any path PMTU change. The
recommended probing interval is 10 minutes per RFC1981. Probing
interval could be sysctled by sysctl_tcp_probe_interval.

Eric Dumazet suggested to implement pseudo timer based on 32bits
jiffies tcp_time_stamp instead of using classic timer for such
rare event.

Current probe_size is chosen by doubling mss_cache,
the probing process will end shortly with a sub-optimal
mss size, and the link mtu will not be taken full
advantage of, in return, this will make user to tweak
tcp_base_mss with care.

Use binary search to choose probe_size in a fine
granularity manner, an optimal mss will be found
to boost performance as its maxmium.

In addition, introduce a sysctl_tcp_probe_threshold
to control when probing will stop in respect to
the width of search range.

Quotes from RFC4821 7.2.  Selecting Initial Values

   It is RECOMMENDED that search_low be initially set to an MTU size
   that is likely to work over a very wide range of environments.  Given
   today's technologies, a value of 1024 bytes is probably safe enough.
   The initial value for search_low SHOULD be configurable.

Moreover, set a small value will introduce extra time for the search
to converge. So set the initial probe base mss size to 1024 Bytes.

Other users users of the neighbour table use neigh->output as the method
to decided when and which link-layer header to place on a packet.
DECnet has been using neigh->output to decide which DECnet headers to
place on a packet depending which neighbour the packet is destined for.

The DECnet usage isn't totally wrong but it can run into problems if the
neighbour output function is run for a second time as the teql driver
and the bridge netfilter code can do.

Therefore to avoid pathologic problems later down the line and make the
neighbour code easier to understand by refactoring the decnet output
code to only use a neighbour method to add a link layer header to a
packet.

This is done by moving the neigbhour operations lookup from
dn_to_neigh_output to dn_neigh_output_packet.

switchdev: add IPv4 routing offload

v4:

  - Add NETIF_F_NETNS_LOCAL to rocker port feature list to keep rocker
    ports in the default netns.  Rocker hardware can't be partitioned
    to support multiple namespaces, currently.  It would be interesting
    to add netns support to rocker device by basically adding another
    match field to each table to match on some unique netns ID, with
    a port knowing it's netns ID.  Future work TDB.
  - Up-level the RTNH_F_EXTERNAL marking of routes installed to offload
    device from driver to switchdev common code.  Now driver can't skip
    routes.  Either it can install the route or it cannot.  Yes or No.
    If no on any route, all offloading is aborted by removing routes
    from offload device and setting ipv4.fib_offload_disabled so no more
    routes can be offloaded.  This is harsh, but it's our starting point.
    We can refine the policies in follow-up work.
  - Add new net.ipv4.fib_offload_disabled bool that is set if anything
    goes wrong with route offloading.  We can refine this later to make
    the setting per-device or per-device-port-netdev, but let's start
    here simple and refine in follow-up work.
  - Rebase against Alex's latest FIB changes.  I think I did everything
    correctly, and didn't run into any issues with testing, but I'd like
    Alex to look over the changes and maybe follow-up with any cleanups.

v3:

Changes based on v2 review comments:

  - Move check for custom rules up earlier in patch set, to keep git bisect
    safe.
  - Simplify the route add/modify failure handling to simple try until
    failure, and then on failure, undo everything.  The switchdev driver
    will return err when route can normally be installed to device, but
    the install fails for one reason or another (no space left on device,
    etc).  If a failure happens, uninstall all routes from the device,
    punting forwarding for all routes back to the kernel.
  - Scan route's full nexthop list, ensuring all nexthop devs belong
    to the same switchdev device, otherwise don't try to install route
    to device.

v2:

Changes based on v1 review comments and discussions at netconf:

  - Allow route modification, but use same ndo op used for adding route.
    Driver/device is expected to modify route in-place, if it can, to avoid
    interruption of service.
  - Add new RTNH_F_EXTERNAL flag to mark FIB entries offloaded externally.
  - Don't offload routes if using custom IP rules.  If routes are already
    offloaded, and custom IP rules are turned on, flush routes from offload
    device.  (Offloaded routes are marked with RTNH_F_EXTERNAL).
  - Use kernel's neigh resolution code to resolve route's nexthops' neigh
    MAC addrs.  (Thanks davem, works great!).
  - Use fib->fib_priority in rocker driver to give priorities to routes in
    OF-DPA unicast route table.

v1:

This patch set adds L3 routing offload support for IPv4 routes.  The idea is to
mirror routes installed in the kernel's FIB down to a hardware switch device to
offload the data forwarding path for L3.  Only the data forwarding path is
intercepted.  Control and management of the kernel's FIB remains with the
kernel.
====================

The driver implements ndo_switch_fib_ipv4_add/del ops to add/del/mod IPv4
routes to/from switchdev device.  Once a route is added to the device, and the
route's nexthops are resolved to neighbor MAC address, the device will forward
matching pkts rather than the kernel.  This offloads the L3 forwarding path
from the kernel to the device.  Note that control and management planes are
still mananged by Linux; only the data plane is offloaded.  Standard routing
control protocols such as OSPF and BGP run on Linux and manage the kernel's FIB
via standard rtm netlink msgs...nothing changes here.

A new hash table is added to rocker to track neighbors.  The driver listens for
neighbor updates events using netevent notifier NETEVENT_NEIGH_UPDATE.  Any ARP
table updates for ports on this device are recorded in this table.  Routes
installed to the device with nexthops that reference neighbors in this table
are "qualified".  In the case of a route with nexthops not resolved in the
table, the kernel is asked to resolve the nexthop.

The driver uses fib_info->fib_priority for the priority field in rocker's
unicast routing table.

The device can only forward to pkts matching route dst to resolved nexthops.
Currently, the device only supports single-path routes (i.e. routes with one
nexthop).  Equal Cost Multipath (ECMP) route support will be added in followup
patches.

This patch is driver support for unicast IPv4 routing only.  Followup patches
will add driver and infrastructure for IPv6 routing and multicast routing.

Call into the switchdev driver any time an IPv4 fib entry is
added/modified/deleted from the kernel's FIB.  The switchdev driver may or
may not install the route to the offload device.  In the case where the
driver tries to install the route and something goes wrong (device's routing
table is full, etc), then all of the offloaded routes will be flushed from the
device, route forwarding falls back to the kernel, and no more routes are
offloading.

We can refine this logic later.  For now, use the simplist model of offloading
routes up to the point of failure, and then on failure, undo everything and
mark IPv4 offloading disabled.

If something goes wrong with IPv4 FIB offload, mark entire net offload
disabled.  This is brute force policy to basically shut down IPv4 FIB offload
permanently if there is a problem offloading any route to an external device.
We can refine the policy in the future, to handle failures on a per-device or
per-route basis, but for now, this policy is per-net.

What we're trying to avoid is an inconsistent split between the kernel's FIB
and the offload device's FIB.  We don't want the device to fwd a pkt
inconsitent with what the kernel would do.  An example of a split is if device
has 10.0.0.0/16 and kernel has 10.0.0.0/16 and 10.0.0.0/24, the device wouldn't
see the longest prefix 10.0.0.0/24 and potentially forward pkts incorrectly.

Limited capacity or limited capability are two ways a route may fail to install
to the offload device.  We'll not differentiate between failures at this time,
and treat any failure as fatal and mark the net as fib_offload_disabled.

Flesh out ndo wrappers to call into device driver.  To call into device driver,
the wrapper must interate over route's nexthops to ensure all nexthop devs
belong to the same switch device.  Currently, there is no support for route's
nexthops spanning offloaded and non-offloaded devices, or spanning ports of
multiple offload devices.

Since switch device ports may be stacked under virtual interfaces (bonds and/or
bridges), and the route's nexthop may be on the virtual interface, the wrapper
will traverse the nexthop dev down to the base dev.  It's the base dev that's
passed to the switchdev driver's ndo ops.

This series contains updates to i40e only.

Greg provides fixes for the NPAR transmit scheduler where the driver
initialization caused the BW configurations to not take effect, so use
a BW configuration read and write back to "kick" the transmit scheduler
into action.  Fixes the ethtool offline test, where we were not actually
taking the device offline before doing the testing.

Matt modifies the get and set LED functions so they ignore activity LEDs
since we are required to blink the link LEDs only.

Neerav provides a workaround for whenever a DCBX configuration is changed,
where the firmware doe not set the operational status bit of the
application TLV status as returned from the "Get CEE DCBX Oper Cfg" admin
queue command.  So remove the check for the operational and sync bits of
the application TLV status until a firmware fix is provided.

Shannon changes the driver to grab the NVM devstarter version and not
the image version, since it is the more useful version and is what
should be displayed.  Moves the IRQ tracking setup and tear down into
the same routines that do the IRQ setup and tear down.  This keeps
like activities together and allows us to track exactly the number
of vectors reserved from the OS, which may be fewer than are available
from the hardware.

Jesse provides a fix to use a more portable sign extension by replacing
0xffff.... with ~(u64)0 or ~(u32)0.  Also fixes XPS mask when resetting,
where the driver would accidentally clear the XPS mask for all queues
back to 0.  This caused higher CPU utilization and had some other
performance impacts for transmit tests.  Cleans up some whitespace
formatting.

Catherine provides a fix where some firmware versions are incorrectly
reporting a breakout cable as PHY type 0x3 when it should be 0x16
(I40E_PHY_TYPE_10GBASE_SFPP_CU).  Adds the 10G and 40G AOC PHY types
to the case statement in get_media_type and ethtool get_settings so
that the correct information gets reported back to the user.

Anjali provides IOREMAP changes for future device support, where we
do not want to map the whole CSR space since some of it is mapped by
other drivers with different mapping methods.

cxgb4: RX Queue related cleanup and fixes

This patch series adds a common function to allocate RX queues and queue
allocation changes to RDMA CIQ

The patches series is created against 'net-next' tree.
And includes patches on cxgb4 driver.

We have included all the maintainers of respective drivers. Kindly review the
change and let us know in case of any review comments.

To allow for better scalability on systems with large core counts, we
will try and allocate enough RDMA Concentrator IQs and MSI/X vectors as
we have cores. If we cannot get enough MSI/X vectors, fall back to the
minimum required: 1 per adapter rx channel.

Also clean up cxgb_enable_msix() to make it readable and correct a bug
where the vectors are not correctly assigned if the driver doesn't get
the full amount requested.

This extends the design in commit 95850116 ("bridge: Add support for
IEEE 802.11 Proxy ARP") with optional set of rules that are needed to
meet the IEEE 802.11 and Hotspot 2.0 requirements for ProxyARP. The
previously added BR_PROXYARP behavior is left as-is and a new
BR_PROXYARP_WIFI alternative is added so that this behavior can be
configured from user space when required.

In addition, this enables proxyarp functionality for unicast ARP
requests for both BR_PROXYARP and BR_PROXYARP_WIFI since it is possible
to use unicast as well as broadcast for these frames.

The key differences in functionality:

BR_PROXYARP:
- uses the flag on the bridge port on which the request frame was
  received to determine whether to reply
- block bridge port flooding completely on ports that enable proxy ARP

BR_PROXYARP_WIFI:
- uses the flag on the bridge port to which the target device of the
  request belongs
- block bridge port flooding selectively based on whether the proxyarp
  functionality replied

The PF driver spams the system log with messages about VF VSI when VFs
are created, as well as each time they are reset. This is annoying, and
the information isn't even useful most of the time.

Remove this message to reduce user annoyance.

Move the IRQ tracking setup and teardown into the same routines that
do the IRQ setup and teardown.  This keeps like activities together and
allows us to track exactly the number of vectors reserved from the OS,
which may be fewer than are available from the HW.
