80003 NICs and NICs found on ICH8 mobos, and improves support for
already known chips.
Details:
- if_em.c. Merged manually, viewing diff between new vendor
driver and previous one. This was an easy task, because
most changes between 5.1.5 and 6.0.5 are bugfixes taken
from FreeBSD.
- if_em_hw.h. Dropped in from vendor, and then restored
revisions 1.16, 1.17, 1.18.
- if_em_hw.c. Dropped in from vendor, and then restored
revision 1.15.
- if_em_osdep.h. Added new required macros from vendor file
and add a hack against define namespace mangling in
if_em_hw.h. Intel made another hack, but I prefer mine.
