2014-01-03i40e: refactor VF reset flowMitch Williams
Fix the VF reset flow so that it works on real hardware. After discussions with the HW team, the reset flow has been changed somewhat. - Change the i40e_reset_vf function to a void type, and fix up the callers to reflect this. - Move the MSI-X disable code to i40e_free_vf_res since it must be done every time the VF is freed, regardless of whether or not it is reset. - Ensure that the PCIe bus is quiet before polling the reset bit. - Don't clear the VFGEN_RSTAT1 register at the beginning as it is cleared by the reset. - Poll longer for the reset to be done. - Disable the queues using an existing function rather than rolling our own. - Free and reallocate the VSI after reset to avoid rx hang.

2014-01-03i40e: move i40e_reset_vfMitch Williams
The VF reset code will be refactored in future patches. Part of that refactor required it to call i40e_alloc_vf_res and i40e_free_vf_res, so the function must be moved. In order to make the future patches more readable, we perform the function move here, with no other changes.

2014-01-03i40e: add wake-on-lan supportShannon Nelson
Wake on LAN is disabled by default and will remain that way for most platforms, but there is an NVM setting that allows vendors to enable it for a port if they think they've provided the right power environment for the device. This patch adds code to check the NVM setting and enable Magic Packet use if WoL is enabled for the port. Since only Magic Packet is supported, there's not a lot of HW configuration needed.

2014-01-03i40e: Suppress HMC error to Interrupt message levelAnjali Singhai Jain
The HMC error interrupt would generate an un-necessary message "unhandled interrupt", causing extra log spam, in addition to causing a reset that was not necessary. Prevent this issue by handling the HMC error case explicitly, and only reset if the interrupt was from some of the other causes.

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.

Arik is reworking the transport API by unifying redudant APIs and making error handling more generic. Eyal keeps on digging in the rate scaling code. 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."
