ixgbe: Update shared code

[kbowling]

Summary

Sync the ixgbe shared code with DPDK shared code which has local fixes. Some judgement was applied during the merge, there are some features DPDK disabled (2.5G and 5G autoneg due to interop issues), and we support bypass adapters.

"not-released-cid-ixgbe.2020.06.09.tar.gz"

Obtained from: DPDK http://git.dpdk.org/dpdk/tree/drivers/net/ixgbe/base

Test Plan

Testing on x550em (Xeon-D)

Update with remaining catch-up diff

@imp For posterity, the way I generated the patches.. @erj maybe the DPDK team can use a method like this too so we stay in lockstep

Generate a patch file from the DPDK git repo:

git format-patch -1 <commit sha>

Merge it in the FreeBSD src git repo:

git am -p5 --reject --directory sys/dev/ixgbe ~/c/os/dpdk/drivers/net/ixgbe/base/0001-net-ixgbe-base-increase-the-timeout.patch

# If I need to fix it up, hack hack
git add <file>
git am --continue

Edit the commit message to include FreeBSD metadata:

git commit --amend

I'd like to commit this on the 27th (2 week feedback window) if there is no other discussion.

Ping. Awaiting approval
