When a client moves from a DSA user port to a software port in a bridge, it cannot reach any other clients that connected to the DSA user ports. That is because SA learning on the CPU port is disabled, so the switch ignores the client's frames from the CPU port and still thinks it is at the user port. Fix it by enabling SA learning on the CPU port. To prevent the switch from learning from flooding frames from the CPU port, set skb->offload_fwd_mark to 1 for unicast and broadcast frames, and let the switch flood them instead of trapping to the CPU port. Multicast frames still need to be trapped to the CPU port for snooping, so set the SA_DIS bit of the MTK tag to 1 when transmitting those frames to disable SA learning.
