Thanks, committed.

You can get this info with iwpriv ath0 get_driver_caps but you then have to 
interpret the decimal number to figure out the ciphers; e.g.

iwpriv ath0 get_driver_caps
ath0	get_driver_caps:255247

255247 = 0x3e50f = 
	IEEE80211_C_WEP
	IEEE80211_C_TKIP
	IEEE80211_C_AES
	IEEE80211_C_AES_CCM
	IEEE80211_C_IBSS
	IEEE80211_C_HOSTAP
	IEEE80211_C_SWRETRY
	IEEE80211_C_TXPMGT
	IEEE80211_C_SHSLOT
	IEEE80211_C_SHPREAMBLE
	IEEE80211_C_MONITOR
	IEEE80211_C_TKIPMIC

from which you can see ciphers.
