Remove net/wireless.h (because there also is the linux/wireless.h) and subsume everything into net/cfg80211.h -- except the definitions for regulatory structures which get moved to a new header net/regulatory.h. The "new" net/cfg80211.h is now divided into sections. There are no real changes in this patch but code shuffling and some very minor documentation fixes. I have also, to make things reflect reality, put in a copyright line for Luis to net/regulatory.h since that is probably exclusively written by him but was formerly in a file that only had my copyright line.

In the past, we didn't limit the amount of active tx urbs. However, ar9170 only has a limited buffer reserved for pending data frames. This wasn't much of a problem with the slower 802.11b/g. We simply stopped the full queue and moved on to something different in the mean time. But - as you guessed it - this simple approach stands in way for a decent aggregation implementation.
