description:
Remove '__attribute__((__packed__))' from structure definisions
for Am7990 LANCE registers where no implicit padding is expected.

gcc 4.5.3 seems to generate strange and wrong instructions
(four moveb insns against u_short members) if packed attribute
is specified in this case, then netboot fails immediately.

Should be pulled up to netbsd-6.
