With this patch JOIN and CONFIG_BSS commands are confirmed
successfully but for some reason AUTH packet is not sent into the air.
I'll prepare firmware logs so we can send them to firmware engineers,
may be they will notice some problem. From first look it seems like
something wrong with output power.
