I have applied your patch, but all I get is:
# ifconfig -v rl0 caps
Capabilities: 48
I would love to see for wired NICs something like:
ifconfig -m ath0 list caps
ath0=6783edcf<WEP,TKIP,AES,AES_CCM,FF,TURBOP,IBSS,HOSTAP,AHDEMO,TXPMGT,SHSLOT,SHPREAMBLE,MONITOR,TKIPMIC,WPA1,WPA2,BURST,WME,BGSCAN,TXFRAG>
Amazing stuff :-) I wish I could hack that.
