net: dsa: mt7530: add support for port mirroring
Add support for configuring port mirroring through the cls_matchall classifier. We do a full ingress and/or egress capture towards a capture port. MT7530 supports one monitor port and multiple mirrored ports. Signed-off-by: DENG Qingfang <dqfext@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
