IEEE 802.11 protocol does not support such a configuration, i.e., the
wireless station interface cannot send frames with the source address
being different from its own.

That sounds very strange.. I'm not sure how exactly you are setting this
up, but if this is layer 2 bridging to a wireless station interface, it
won't work regardless of what security mode you are using unless
something like 4-address WDS frames are used.
