IEEE 802.11 allows only the own MAC address to be used as the source
address (addr2) when operating as a non-AP STA in BSS (client in Managed
mode). In other words, layer 2 bridging does not work properly. AP mode
and WDS links can be used for bridging without problems, but this will
of course require the driver to support these.
