ixgbe(4): Update to version 3.1.13-k

[erj]

Summary

Adds support for two new devices: X552 SFP+ 10 GbE, and the single port version of X550T.

Along with more of a changelist that I need to compile.

Test Plan

We've run various tests on the standalone version that this version of the driver is derived from, along with compiling this diff into a CURRENT kernel and verifying that the kernel boots, and the interfaces appear in ifconfig and pass traffic. (On a system with an X520 and an X540).

[hiren]

It wasn't clear from the summary that if this just adds new devices or also updates existing ones.

Do you guys run any sort of performance tests to make sure you don't make existing drivers worse with new changes? If not, that is a good/necessary thing to do.

[gnn]

I'd like to see this broken down into a smaller set of changes. Single large changes like this are hard to review, debug, and, if there are problems, revert.

[erj]

Ok, will do. I wish there was a nice way to lump a bunch of diffs together into one revision in Phabricator, though.

That said, could someone do an "arc patch D4186" and tell me if this compiles and doesn't egregiously break something they're running?

[sbruno]

applies cleanly, build started.

I see no objections here, so this should be committed.
