* iwlwifi: mvm: Set RRM_ENABLED bit in scan commandsAndrei Otcheretianski2014-09-164-2/+31
| | | | | | | | | | | | Set RRM_ENABLED (bit 6) flag in scan commands. When this flag is set the fw will add WFA vendor-specific TPC report and DS parameter set IEs into probe requests. This bit is set for SCAN_OFFLOAD_REQUEST_CMD(0x51).

| | | | | | | | | | | | | | Introduce new tx command flag (TX_CMD_FLG_WRITE_TX_POWER) which requests the fw to update the tx power value at some constant offset. Set this flag when transmitting either TPC report or Link measurement report action frames. In addition, introduce new tlv which indicates whether the fw supports power insertion (IWL_UCODE_TLV_CAPA_TXPOWER_INSERTION_SUPPORT) and publish the corresponding nl80211 feature.

The sorted list of rates according throughput is extended to the best four rates as we need them in upcoming joint rate and power control. The sorting is done via the new function minstrel_ht_sort_best_tp_rates().

| * mac80211: support DTPC IE (from Cisco Client eXtensions)Steinar H. Gunderson2014-09-084-12/+77
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Linux already supports 802.11h, where the access point can tell the client to reduce its transmission power. However, 802.11h is only defined for 5 GHz, where the need for this is much smaller than on 2.4 GHz. Cisco has their own solution, called DTPC (Dynamic Transmit Power Control). Cisco APs on a controller sometimes but not always send 802.11h; they always send DTPC, even on 2.4 GHz. This patch adds support for parsing and honoring the DTPC IE in addition to the 802.11h element (they do not always contain the same limits, so both must be honored); the format is not documented, but very simple. Tested (on top of wireless.git and on 3.16.1) against a Cisco Aironet 1142 joined to a Cisco 2504 WLC, by setting various transmit power levels for the given access points and observing the results. The Wireshark 802.11 dissector agrees with the interpretation of the element, except for negative numbers, which seem to never happen anyway. Signed-off-by: Steinar H.

| * mac80211: fix broken use of VHT/20Mhz with some APsEyal Shapira2014-09-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit "mac80211: disable 40MHz support in case of 20MHz AP" broke working VHT in 20Mhz with APs like Netgear R6300v2 which do not publish support for 40Mhz but allow use of VHT in 20Mhz. The break is because VHT is disabled once no HT cap doesn't indicate support for 40Mhz. This causes the assoc request to be sent without any VHT IE and the association is only HT due to this.

| * | iwlwifi: mvm: fix quota update avoidanceJohannes Berg2014-09-141-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When not updating the quota, the new command shouldn't be stored as otherwise slowly drifting quota would never update the firmware. Fix this by storing the command only when it was also sent. Since the error message also only makes sense when attempting to send the command, just short-circuit the function when there's no need to send the command.

| * | iwlwifi: mvm: use the firmware to get the temperature during CT killLuciano Coelho2014-09-145-257/+140
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reading the temperature directly from the hardware, without the help of the firmware, is a complex process and is not entirely the same for different hardware. Also, some NICs don't easily allow access to the sensors when the firmware is not running, which would add even more complexity to the code. To reduce the code complexity and to avoid code duplication between the firmware and the driver, boot the firmware briefly to read the current temperature while in CT kill mode.
