--------------------
I apologize for not having sent this sooner. FWIW, I was in a car
somewhere between Illinois and North Carolina for most of the day
Sunday and Monday... :-)
This is (obviously) the last non-fix pull request for wireless bits
intended for 3.5. It includes AP support for mwifiex, a variety of HCI
and other updates for NFC, some brcmfmac and brcmsmac refactoring,
a large batch of ssb and bcma updates, a batch of ath6kl updates,
some cfg80211 and mac80211 updates/refactoring from Johannes Berg,
a rather large collection of Bluetooth updates by way of Gustavo,
and a variety of other bits here and there.
