I have an AP and 2 stations. The wifi interfaces on the stations are in bridges. Pinging from one station to the other generates this error. This does not occur if the station interfaces are not in a bridge. The bridge puts the station wifi interface in promiscuous mode. After instrumenting the bridge code, the following seems to be happening. In the case of a frame sent from S1->AP->S2, S1 also receives the AP->S2 frame. When that frame is converted to 802.3, S1 is the source address and the bridge code complains. I don't understand why the station interface needs to be in promiscuous mode. The 4addr frames would seem to make this unnecessary. As a test, I ignored promiscuous mode for stations in the ath9k driver (a hack) and the messages disappeared. The setup then functions as a client bridge in that computers hooked to one station can ping computers connected to the other station. I think this is a bug.
