em(4) update for 6-STABLE

[Thomas]

Hi Gleb

Thanks for you work.
I will test this on a small freebsd based router with an averrage of
300mb/s in the next few days.
Should I test anything special? Where should I see most of the
improvements compared to 6.1 Release? (less interrupts without polling?)

Cheers,
Thomas
