Yeah wireless-testing is best for that. I should also mention that if
you want to use AP mode you want to be at least on 2.6.29 (your own
kernel, not the compat-wireless one) if you care about Power Save
buffering on the AP as otherwise even if you use a compat-wireless
with code from > 2.6.29 those frames will be dropped. IIRC its due to
the way we use skb->cb for this and there not being a clean way to
backport this (so we just drop them).
