Hi,
I'm not sure if this is the best list.
I'm trying to get our Avila (arm) boards with atheros wireless cards
upgraded from 7.2 to 8.0. We use adhoc mode and I get a panic in
ieee80211_getcapinfo() because the chan pointer is 0xffff which seems
to mean IEEE80211_CHAN_ANY in other places. So the question is, should
ieee80211_getcapinfo() never be called with chan being 0xffff or should
it know how to handle that case?
John
