4dab5c3769 Part 1 of two parts, this is the shared code changes in
support of new deltas for both em and igb drivers.

Note that I am not able to track all the bugs fixed in
this code, I am a consumer of it as a component of my
core drivers. It is important to keep the FreeBSD drivers
up to date with it however.

One important note is there is a key fix for 82574 in this
update. Also, there are lots of white space changes, I am
not happy about them but have no control over it :)

f0ecc46d04 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!!

b827058579 OK, I was a bit sleep this morning and checked in
the core changes but left out the shared code, lol.
Well, and a couple fixes to the core... hopefully
this will all be complete now.

Happy happy joy joy :)
