Hi, i don't know mutch about ibss mode, but in 802.11s we expirience massive
packetloss sometime, also according to signal levels ani seems not work at all,
it adjust some level while interface startup, then it stay forether, levels
varies about from -10 to -60db dBm, for example - rmmod then insmod, bring interface
up - see one level, rmmod then insmod, bring interface up - another level,
and so on, also seems issuing scan make some level ajust, in random side too.
but as i say before - i dont familiar with ani, i just make it work in 802.11s
mode as in AP mode and this helps. you can try of cose my patch, just change
NL80211_IFTYPE_MESH_POINT to NL80211_IFTYPE_ADHOC, but i don't known make it
sence or not.
