Glad that it worked this far -

since the driver is not used I was expecting that it would not
work so well -

at this point you'll need to 'get your hands dirty' as it were -

It does look like there is a good deal of debug printing in the driver -
you might set:

#define DEBUG_INIT  1
#define DEBUG_IOCTL 1
#define DEBUG_HW    1

instead of '0' in in sys/dev/netif/e1000/if_em.h and rebuild the driver
to see if that provides a useful hint on where it fails.

 From there, I'd probably cross-check against the 'live' netif/em driver
to see any differences in this known-working older version that look
like they should be moved into the e1000/em copy, then retry,
repeat, etc. until either you have a working driver or you quit :D

of course I'm sure the usual suspects will be happy to answer questions
should you happen on them.

Good luck!

- Chris
