This is a good point actually, which I thought about, but did not give a
lot of importance to for the moment. Either we go full steam ahead with
assisted learning on the CPU port for everybody, and we selectively
learn the addresses relevant to the bridging funciton only, or we do
what you say, but then it will be a little bit more complicated IMO, and
have hardware dependencies, which isn't as nice.

Are skb->offload_fwd_mark and source DSA switch kept in dsa_slave_xmit?
I think SA learning should be bypassed iff skb->offload_fwd_mark == 1 and
source DSA switch == destination DSA switch.
