Merge branch 'for-davem' of git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next
John W. Linville says: ==================== Here is another batch of updates intended for 3.7... Highlights include an hci_connect re-write in Bluetooth, HCI/LLC layer separation in NFC, removal of the raw pn544 NFC driver, NFC LLCP raw sockets support, improved IBSS auth frame handling in mac80211, full-MAC AP mode notification support in mac80211, a lot of attention paid to brcmfmac, and the usual level of updates to iwlwifi, ath9k, mwifiex, and rt2x00, and various other updates. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
