====================
pull request: wireless 2014-07-10

Please pull this batch of fixes intended for the 3.16 stream!

For the iwlwifi bits, Emmanuel says:

"I have here 2 patches that disable the usage of CTS to self. This
keeps making trouble to the firmware and is not a really reliable
protection anyway. We may re-enable it in the future, but in rarer
cases. Along with this, I have a fix from Ilan that prevents a
firmware assertion."

On top of that...

Amitkumar Karwar provides an mwifiex fix to properly initialize
(i.e. zero) tx_info/rx_info.

Andrea Merello stops rt2800usb from doing DMA operations on the
stack...yikes!
