Currently, there is only a warning if a packet enters the bridge

Clearly this indicates a network loop (or even spoofing) so we
generally do not want to process the packet. Therefore, move the check
already done for 802.1x scenarios up and do it unconditionally.

Does 802.1d say anything about this?

Quoting the standard gives you a strong case for getting the patch
merged.
