This is not a driver limitation; the IEEE 802.11 protocol itself does not support such a mechanism when the WLAN card is in managed mode (connected to an AP). You could use bridging if you were to run ath9k in AP mode, but that does not sound like something that would fit in nicely with your setup. The other option could be to use WDS (4-address frame format) links which could also providing bridging. Though, I do not know whether they can currently be used with mac80211 and/or ath9k. - Jouni
