2013-12-18brcmfmac: use consistent function names in dhd_sdio.cArend van Spriel

2013-12-18brcmfmac: Combine protocol push hdr and bus txdata.Hante Meuleman
For the transmission of data a protocol push hdr is performed followed by a bus txdata call. For the new protocol msgbuf this is not workable. Since they are already "loosely" coupled for bcdc protocol they are combined. This means that txdata will go "through" the protocol layer and a seperate protocol push hdr will not be needed anymore.

Commit [3469adb3: fix potential NULL pointer dereference] introduced a check of msg_ind allocation, but omitted allocation of msg_ind->msg. Moreover, it introduced two if statements, which looked a bit clunky.

FW still does not support power management on multiple MAC interfaces. Currently the driver enforce this limitation by disabling PM if second interface is added. Change this behavior to allow PM on a single interface even if other interfaces exist but not bound to any specific PHY. PM will be enabled if only one single interface is bound.

2013-12-17iwlwifi: mvm: Add uAPSD misbehaving AP notification handlingAlexander Bondar
FW implements protective algorithm to identify AP's improper uAPSD behavior. FW sends misbehaving AP notification in this case. Add this notification handling. Avoid using uAPSD in next association to the exactly same AP. Refactor iwl_mvm_power_build_cmd() to move uAPSD related code to a separate function.

2013-12-17iwlwifi: publish Tx STBC support in VHTEyal Shapira
If the device is MIMO and VHT capable it supports Tx STBC. Unlike HT, any chip that supports VHT also support STBC so no need for a config parameter. Using num_of_ants multiple times warranted caching it. Signed-off-by: Eyal Shapira <eyal@wizery.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2013-12-17iwlwifi: set VHT beamformee STS cap correctlyEyal Shapira
It was set to zero which reflects support of a single STS. Set according to the number of Rx antennas which correctly reflects the number of STSs the STA can receive in a VHT NDP. This improves beamforming and has been tested to improve Rx throughput.
