This adds a PHC to the mlx4_en driver. We use reader/writer spinlocks to
protect the timecounter since every packet received needs to call
timecounter_cycle2time() when timestamping is enabled. This can become
a performance bottleneck with RSS and multiple receive queues if normal
spinlocks are used.
This driver has been tested with both Documentation/ptp/testptp and the
linuxptp project (http://linuxptp.sourceforge.net/) on a Mellanox
ConnectX-3 card.

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.
