====================
pull request: wireless 2014-09-05

Please pull this batch of fixes intended for the 3.17 stream...

For the mac80211 bits, Johannes says:

"Here are a few fixes for mac80211. One has been discussed for a while
and adds a terminating NUL-byte to the alpha2 sent to userspace, which
shouldn't be necessary but since many places treat it as a string we
couldn't move to just sending two bytes.

In addition to that, we have two VLAN fixes from Felix, a mesh fix, a
fix for the recently introduced RX aggregation offload, a revert for
a broken patch (that luckily didn't really cause any harm) and a small
fix for alignment in debugfs."

For the iwlwifi bits, Emmanuel says:

"I revert a patch that disabled CTS to self in dvm because users
reported issues. The revert is CCed to stable since the offending
patch was sent to stable too. I also bump the firmware API versions
since a new firmware is coming up. On top of that, Marcel fixes a
bug I introduced while fixing a bug in our Kconfig file."

Please let me know if there are problems!
