Well, it's just that we had some issues with specific hardware and felt =
that the hardware was much better supported in the em driver. The =
current NetBSD driver is 3500 lines against 11400 for the one coming =
from FreeBSD. The lower layer part of the driver (5000 lines) is =
dedicated to tuning of the different boards.
For those interested, the source code is available via anonymous FTP at =

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?
