2014-01-03tg3: Poll cpmu link state on APE + ASF enabled devicesNithin Sujir
On ASF enabled devices where the mgmt firmware runs on the application processing engine, there is a race between the tg3 driver processing a link change event and the ASF firmware clearing the link changed bit in the EMAC status register. This leads to link notifications to the driver sometimes getting lost. Poll the CPMU link state as a backup for the normal interrupt path update if ASF is enabled.

2014-01-03tg3: Set the MAC clock to the fastest speed during boot code loadNithin Sujir
On the 5717, 5718 and 5719 devices, the bootcode runs slower when any port doesn't have a link due to clock speed slowing down as part of the link-aware feature. This leads to the driver timing out waiting for the bootcode signature. This patch overrides the clock policy to the highest frequency just before reset and restores it after the bootcode is up.

2014-01-03sh_eth: coding style fixesSergei Shtylyov
Running 'scripts/checkpatch.pl' on the driver files gives numerous warnings: - block comments using empty /* line; - unneeded \ at end of lines; - message string split across lines; - use of __attribute__((aligned(n))) instead of __aligned(n) macro; - use of __attribute__((packed)) instead of __packed macro. Additionally, running 'scripts/checkpatch.pl --strict' gives more complaints: - including the paragraph about writing to FSF into the heading comment; - alignment not matching open paren; - multiple assignments on one line; - use of CamelCase names; - missing {} on one of the *if* arms where another has them; - spinlock definition without a comment. While fixing these, also do some more style cleanups: - remove useless () around expressions; - add {} around multi-line *if* operator's arm; - remove space before comma; - add spaces after /* and before */; - properly align continuation lines of broken up expressions; - realign comments to the structure fields.

2014-01-02mlx4_en: Add PTP hardware clockShawn Bohrer
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.

2014-01-02ipv4: arp: update neighbour address when a gratuitous arp is received and ↵Salam Noureddine
arp_accept is set 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.
