Well, I really do think that AP development is stuck due to nobody testing it. So, something like the following patch? http://foobar would be some page on wireless.kernel.org describing what additional patches are needed for the latest wireless-testing kernel. Additionally we might want to put this into wireless-testing only. There's not a big need for pushing this upstream. If somebody wants to test AP mode, he'll need to get wireless-testing anyway. Subject: mac80211: allow AP and VLAN modes This patch is based on a patch by Johannes Berg. It allows switching interfaces into AP/VLAN modes using cfg80211 (nl80211). Don't allow doing it with wext because then people will just attempt to do it manually (without hostapd) and complain that it doesn't work.
