asix: check packet size against mtu+ETH_HLEN instead of ETH_FRAME_LEN
Driver checks received packet is too large in asix_rx_fixup() and fails if it is. Problem is that MTU might be set larger than 1500 and asix fails to work correctly with VLAN tagged packets. The check should be 'dev->net->mtu + ETH_HLEN' instead. Tested with AX88772. Signed-off-by: Jussi Kivilinna <jussi.kivilinna@mbnet.fi> Signed-off-by: David S. Miller <davem@davemloft.net>
