Major changes:
- Add i219/i219(2) hardware support. (Found on Skylake generation and newer
chipsets.)
- Further to the last Skylake support diff, this one also includes support for
the Lewisburg chipset (i219(3)).
- Add a workaround to an igb hardware errata.
All 1G server products need to have IPv6 extension header parsing turned off.
This should be listed in the specification updates for current 1G server
products, e.g. for i350 it's errata #37 in this document:
http://www.intel.com/content/dam/www/public/us/en/documents/specification-updates/ethernet-controller-i350-spec-update.pdf
- Avoton (i354) PHY errata workaround added
And a bunch of minor fixes, as well as #defines for things that the current
em(4)/igb(4) drivers don't implement.

attach failures on "ICH8" class devices via modifications to
e1000_init_nvm_params_ich8lan()
- Fix compiler warning in 80003es2lan.c
- Add return value handler for e1000_*_kmrn_reg_80003es2lan
- Fix usage of DEBUGOUT
- Remove unnecessary variable initializations.
- Removed unused variables (complaints from gcc).
- Edit defines in 82571.h.
- Add workaround for igb hw errata.
- Shared code changes for Skylake/I219 support.
- Remove unused OBFF and LTR functions.
Tested by some of the folks that reported breakage in previous incarnation.
Thanks to AllanJude, gjb, gnn, tijl for tempting fate with their machines.

igb now has a queue notion that has a single interrupt
with an RX/TX pair, this will reduce the total interrupts
seen on a system. Both em and igb have a new watchdog
method. igb has fixes from Pyun Yong-Hyeon that have
improved stability, thank you :)
I wish to MFC this for 7.3 asap, please test if able.
will sometimes fail to initialize problem due to a lock
contention with management hardware. However, in order to
deliver that fix it was necessary to take a shared code
update as a whole, and this required scattered changes in
the core code to be compatible.
The em driver now has VLAN HW support added as the igb
driver had previously.
MFC after: ASAP - in time for 7.1 RELEASE
proved to be necessary to make the static drivers work
in EITHER/OR or BOTH configurations. Modules will still
build in sys/modules/igb or em as before.
This also updates the igb driver for support for the 82576
adapter, adds shared code fixes, and etc....
MFC after: ASAP
