2014-03-09iwlwifi: nvm: fix VHT capability antenna-dependent fieldsJohannes Berg1-8/+11
As the antenna dependent fields depend on the firmware file and not the NVM, use those fields in the VHT capability creation. Additionally, fix the STBC and antenna pattern consistency fields.

2014-02-23iwlwifi: nvm: remove reading valid antennas from NVMJohannes Berg1-17/+0
These values aren't used as the firmware values should be used, so reading them is pointless and hides potential errors when somebody uses these values. Leave them zero to make it clearer that they can't be used. We can't remove the struct members as the DVM driver does read the values from EEPROM/OTP and the structure is shared between drivers.

2014-02-02iwlwifi: mvm: don't allow A band if SKU forbids itEmmanuel Grumbach1-0/+5
The driver wasn't reading the NVM properly. While this didn't lead to any issue until now, it seems that there is an old version of the NVM in the wild. In this version, the A band channels appear to be valid but the SKU capabilities (another field of the NVM) says that A band isn't supported at all. With this specific version of the NVM, the driver would think that A band is supported while the HW / firmware don't. This leads to asserts.

2014-01-13iwlwifi: mvm: don't use highest rate in VHT MCS SetEyal Shapira1-6/+0
Keeping this as 0 is ok according to spec section 9.7.11 as this means the limits are according to the Tx/Rx supported MCS x NSS bitmap. Initially we've set these as there were concerns of interop issues but these turned out to be false.

2013-12-17iwlwifi: publish Tx STBC support in VHTEyal Shapira1-2/+6
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 Shapira1-0/+3
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.

2013-11-25cfg80211: consolidate passive-scan and no-ibss flagsLuis R. Rodriguez1-2/+2
These two flags are used for the same purpose, just combine them into a no-ir flag to annotate no initiating radiation is allowed. Old userspace sending either flag will have it treated as the no-ir flag. To be considerate to older userspace we also send both the no-ir flag and the old no-ibss flags. Newer userspace will have to be aware of older kernels.
