Jack F Vogel daf9197cff This delta is primarily a fix for es2lan devices that
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
