Recently I updated the sctp socket option deprecation warnings to be both a bit
more clear and ratelimited to prevent user processes from spamming the log file.
Ben Hutchings suggested that I add the process name and pid to these warnings so
that users can tell who is responsible for using the deprecated apis.  This
patch accomplishes that.

Netdev_priv performs an addition, not a pointer dereference, so it seems
quite unlikely that its result would ever be NULL.

A semantic patch that makes this change is as follows:

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.

"I have hear quite a few things. Alex continues his work on power
management. Arik is reworking the transport API by unifying redudant
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
cipher infrastructure in mac80211, and Lilach implements the smart fifo
which allows to save power by making interrupt coalescing smarter."
