The wm driver in -current supports the latest Intel Gig-E boards/chips, 
too.  I don't see any reason to pull in the "em" driver from FreeBSD, 
particularly considering that it won't work on all of the platforms 
that the current "wm" driver works on.

It would be interesting to perhaps tweak the tuning of the current "wm" 
driver, however.  Do you have specific examples of tuning differences 
between the drivers?
