Make sure the NIC drops packets that are larger than the
specified MTU.
The front end of the NIC will accept packets larger than MTU and
will copy all the data it can to fill up the driver's posted
buffers - if the buffers are not long enough the packet will
then get dropped. With the Rx SG buffers allocagted as full
pages, we are currently setting up more space than MTU size
available and end up receiving some packets that are larger
than MTU, up to the size of buffers posted. To be sure the
NIC doesn't waste our time with oversized packets we need to
lie a little in the SG descriptor about how long is the last
SG element.
At dealloc time, we know the allocation was a page, so the
deallocation doesn't care about what length we put in the
descriptor.

Currently the max number of channels is limited to 64, which is half of

with more than 64 cores, users may want to utilize more queues.
This patch increases the advertised max number of channels to 128 by

At the same time, the driver still enable no more than 64 channels at

1GbE Intel Wired LAN Driver Updates 2020-01-06
This series contains updates to igc to add basic support for
timestamping.
Vinicius adds basic support for timestamping and enables ptp4l/phc2sys
to work with i225 devices. Initially, adds the ability to read and
adjust the PHC clock. Patches 2 & 3 enable and retrieve hardware
timestamps. Patch 4 implements the ethtool ioctl that ptp4l uses to
check what timestamping methods are supported. Lastly, added support to
do timestamping using the "Start of Packet" signal from the PHY, which
is now supported in i225 devices.
While i225 does support multiple PTP domains, with multiple timestamping
registers, we currently only support one PTP domain and use only one of
the timestamping registers for implementation purposes.

====================
ethtool: allow nesting of begin() and complete() callbacks
The ethtool ioctl interface used to guarantee that ethtool_ops callbacks
were always called in a block between calls to ->begin() and ->complete()
(if these are defined) and that this whole block was executed with RTNL
lock held:
rtnl_lock();
ops->begin();
/* other ethtool_ops calls */
ops->complete();
rtnl_unlock();
This prevented any nesting or crossing of the begin-complete blocks.
However, this is no longer guaranteed even for ioctl interface as at least
ethtool_phys_id() releases RTNL lock while waiting for a timer. With the
introduction of netlink ethtool interface, the begin-complete pairs are
naturally nested e.g. when a request triggers a netlink notification.
Fortunately, only minority of networking drivers implements begin() and
complete() callbacks and most of those that do, fall into three groups:
- wrappers for pm_runtime_get_sync() and pm_runtime_put()
- wrappers for clk_prepare_enable() and clk_disable_unprepare()
- begin() checks netif_running() (fails if false), no complete()
First two have their own refcounting, third is safe w.r.t. nesting of the
blocks.
Only three in-tree networking drivers need an update to deal with nesting
of begin() and complete() calls: via-velocity and epic100 perform resume
and suspend on their own and wil6210 completely serializes the calls using
its own mutex (which would lead to a deadlock if a request request
triggered a netlink notification). The series addresses these problems.

Unlike most networking drivers using begin() and complete() ethtool_ops
callbacks to resume a device which is down and suspend it again when done,
epic100 does not use standard refcounted infrastructure but sets device
sleep state directly.
With the introduction of netlink ethtool interface, we may have nested
begin-complete blocks so that inner complete() would put the device back to
sleep for the rest of the outer block.
To avoid rewriting an old and not very actively developed driver, just add
a nesting counter and only perform resume and suspend on the outermost
level.

The wil6210 driver locks a mutex in begin() ethtool_ops callback and
unlocks it in complete() so that all ethtool requests are serialized. This
is not going to work correctly with netlink interface; e.g. when ioctl
triggers a netlink notification, netlink code would call begin() again
while the mutex taken by ioctl code is still held by the same task.
Let's get rid of the begin() and complete() callbacks and move the mutex
locking into the remaining ethtool_ops handlers except get_drvinfo which
only copies strings that are not changing so that there is no need for
serialization.

server should be running bound to the vrf device with the client run
in the default VRF (the -2 option is meant for validating connection

While technically this is a bug in previous releases, the tests are
