Am I wrong or AR9331 is handled by the ath5k driver?

However in openwrt you will find some patches that are editing these interface
combinations in order to allow IBSS + AP for some drivers (e.g. ath5k or
ath9k..).

This behaviour is not supported upstream for several reasons, therefore if you
look in the kernel source you will never find a combination allowing the
aforementioned schema.
