869db2f9c7 Add support for the new I350 family of 1G interfaces.
- this also includes virtualization support on these devices

Correct some vlan issues we were seeing in test, jumbo frames on vlans
did not work correctly, this was all due to confused logic around HW
filters, the new code should now work for all uses.

Important fix: when mbuf resources are depeleted, it was possible to
completely empty the RX ring, and then the RX engine would stall
forever. This is fixed by a flag being set whenever the refresh code
fails due to an mbuf shortage, also the local timer now makes sure
that all queues get an interrupt when it runs, the interrupt code
will then always call rxeof, and in that routine the first thing done
is now to check the refresh flag and call refresh_mbufs. This has been
verified to fix this type 'hang'. Similar code will follow in the other
drivers.

Finally, sync up shared code for the I350 support.

Thanks to everyone that has been reporting issues, and helping in the
debug/test process!!

cdddb20941 Merge of the source for igb and em into dev/e1000, this
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....
