You can get the latest NFE driver from cvs
cvs -d freebsdanoncvs at anoncvs.FreeBSD.org:/home/ncvs co
src/sys/modules/nfe src/sys/dev/nfe
Also you have to change by hand src/sys/modules/Makefile
cvs -d freebsdanoncvs at anoncvs.FreeBSD.org:/home/ncvs co
src/sys/modules/Makefile
to see the diff, then recompile kernel :) (only lines with "nfe" are
interesting)
While talking about NFE driver, is it planned freebsd-6.2 to ship with it ?
