John W. Linville says:

====================
pull request: wireless 2014-04-17

Please pull this batch of fixes intended for the 3.15 stream...

For the mac80211 bits, Johannes says:

"We have a fix from Chun-Yeow to not look at management frame bitrates
that are typically really low, two fixes from Felix for AP_VLAN
interfaces, a fix from Ido to disable SMPS settings when a monitor
interface is enabled, a radar detection fix from Michał and a fix from
myself for a very old remain-on-channel bug."

For the iwlwifi bits, Emmanuel says:

"I have new device IDs and a new firmware API. These are the trivial
ones. The less trivial ones are Johannes's fix that delays the
enablement of an interrupt coalescing hardware until after association
- this fixes a few connection problems seen in the field. Eyal has a
bunch of rate control fixes. I decided to add these for 3.15 because
they fix some disconnection and packet loss scenarios which were
reported by the field. I also have a fix for a memory leak that
happens only with a very new NIC."

Along with those...

Amitkumar Karwar fixes a couple of problems relating to driver/firmware
interactions in mwifiex.

Christian Engelmayer avoids a couple of potential memory leaks in
the new rsi driver.

Eliad Peller provides a wl18xx mailbox alignment fix for problems
when using new firmware.

Frederic Danis adds a couple of missing debugging strings to the
cw1200 driver.

Geert Uytterhoeven adds a variable initialization inside of the
rsi driver.

Luciano Coelho patches the wlcore code to ignore dummy packet events
in PLT mode in order to work around a firmware bug.
