This sounds very wrong. In switchdev mode, there is no implicit packet
forwarding. User configures that, either by setting up TC filters to
match/forward packets, putting representors in a bridge, etc.
Basically the driver offloads whatever configuration on representors the
user does, in case it supports it.

Please make sure you follow that.
