ethernet/dlink: use core min/max MTU checking
dl2k: min_mtu 68, max_mtu 1536 or 8000, depending on hardware - Removed change_mtu, does nothing productive anymore sundance: min_mtu 68, max_mtu 8191 CC: netdev@vger.kernel.org CC: Denis Kirjanov <kda@linux-powerpc.org> Signed-off-by: Jarod Wilson <jarod@redhat.com> Signed-off-by: David S.
