Gratuitous arp packets are useful in switchover scenarios to update
client arp tables as quickly as possible. Currently, the mac address
of a neighbour is only updated after a locktime period has elapsed
since the last update. In most use cases such delays are unacceptable
for network admins. Moreover, the "updated" field of the neighbour
stucture doesn't record the last time the address of a neighbour
changed but records any change that happens to the neighbour. This is
clearly a bug since locktime uses that field as meaning "addr_updated".
With this observation, I was able to perpetuate a stale address by
sending a stream of gratuitous arp packets spaced less than locktime
apart. With this change the address is updated when a gratuitous arp
is received and the arp_accept sysctl is set.

APIs and making error handling more generic. Eyal keeps on digging in

We also have two new features - Max is using the brand new generic

This PCI-E SR-IOV virtual function (VF) driver is dependant upon the
physical function (PF) driver (i40e) for nearly all of its hardware
configuration. Requests from the VF driver are passed to the PF using
the hardware's Admin Queue.
This patch contains the functionality for communicating with the PF
driver. Because of the delay inherent in this communications channel,
most of the replies from the PF driver are handled asynchronously. The
exceptions are the "send API version" and "get VF config" messages,
which busy-wait because they are done so early during init that
interrupts are not yet configured.

slight optimization of addr compare for net modules
This is the second patchset for slight optimization of address compare,
mainly for net tree, just following the Joe's opinion, it will help review
the code for maintainers and supports.
v2: Change some style for patch 2.
According Eric's suggestion, use the ether_addr_equal_64bits to instead
of ether_addr_equal for patch 19.
In fact, there are a lot of places which could use ether_addr_equal_64bits
to instead of ether_addr_equal, but not this time, thanks for Joe's
opinion.
v3: Change some style for patch 11/19:
(net: packetengines: slight optimization of addr compare).
Joe pointed out that is_broadcast_ether_addr(addr) would be appropriate here,
but this should be left alone and not in this patch, so fix it later.
In the patch (net: caif: slight optimization of addr compare), the operand for
memcmp is not mac address, so it is unsuitable to use the ether_addr_equal
to compare a non mac address, so remove the patch from the series.
