ixgbe(4): Update HEAD (p3) to 3.2.12-k

[cramerj_intel.com]

Summary

Update to ixgbe including:

• Support for X550EM devices.
• Support for Bypass adapters.
• Flow Director code moved to separate files
• SR-IOV code moved to separate files
• Netmap code moved to separate files

This does NOT contain iflib support. Review D10293 (with iflib support) will be abandoned and a new review will be created to add iflib support.

Test Plan

Work-in-progress. Respectfully request waiting for Jeff's team to perform a validation pass before committing.

In the future when you find yourselves implementing synchronization primitives like swfw_sync or your hand rolled locks in if_bypass.c please make sure you get the attention and sign off from @markj, @jhb, or myself.

This lock needs to be replaced.

Also, can we stop massively refactoring the drivers until after the iflib version goes in to HEAD? And in general, there's a lot of non-productive function shuffling that goes on in Intel drivers that makes it a lot more work for downstream users maintaining their own branches.

Has this code ever been tested with IXGBE_FDIR enabled? This leads to duplicate symbols.
