Thanks, with it I can get AP mode to work on both a 2.4 GHz single
band and a dual band card, but a 5 GHz single band card craps out when
bringing up the interface (see the oops at the end).

I haven't looked to deeply into what's happening, and I haven't made
sure yet the problem isn't caused by any OpenWrt modifications (which
is using compat-wirless 2013-01-07). I'll take a closer look tomorrow.

Regards
Jonas
