You can bridge it on the AP. This is, because in wifi you don't have a source-MAC and a destination-MAC, but also a transmitter-MAC and a receiver-MAC. As an optimisation, in ap2sta direction the destination and the receiver are a single field. In sta2ap direction, the source and the transmitter are a single field
Take a look at 4addr mode which solves the issue by having actually all 4 fields. This is a linux specific implementation and may not be available on all types of cards. An alternative would be to have a routed connection between the two devices and bridge your ovs-instances via GRETAP.
