Just before queuing skb for xmit on port, check if skb has been marked by
switchdev port driver as already fordwarded by device. If so, drop skb. A
non-zero skb->offload_fwd_mark field is set by the switchdev port
driver/device on ingress to indicate the skb has already been forwarded by
the device to egress ports with matching dev->skb_mark. The switchdev port
driver would assign a non-zero dev->skb_mark for each device port netdev
typo: dev->offload_fwd_mark
during registration, for example.
