ethernet/atheros: use core min/max MTU checking
atl2: min_mtu 40, max_mtu 1504
- Remove a few redundant defines that already have equivalents in
if_ether.h.
atl1: min_mtu 42, max_mtu 10218
atl1e: min_mtu 42, max_mtu 8170
atl1c: min_mtu 42, max_mtu 6122/1500
- GbE hardware gets a max_mtu of 6122, slower hardware gets 1500.
alx: min_mtu 34, max_mtu 9256
- Not so sure that minimum MTU number is really what was intended, but
that's what the math actually makes it out to be, due to max_frame
manipulations and comparison in alx_change_mtu, rather than just
comparing new_mtu. (I think 68 was the intended min_mtu value).
