2013-10-18ath9k: add TX99 supportLuis R. Rodriguez12-17/+522
TX99 support enables Specific Absorption Rate (SAR) testing. SAR is the unit of measurement for the amount of radio frequency(RF) absorbed by the body when using a wireless device. The RF exposure limits used are expressed in the terms of SAR, which is a measure of the electric and magnetic field strength and power density for transmitters operating at frequencies from 300 kHz to 100 GHz. Regulatory bodies around the world require that wireless device be evaluated to meet the RF exposure limits set forth in the governmental SAR regulations. In the examples below, for more bit rate options see the iw TX bitrate setting documentation: http://wireless.kernel.org/en/users/Documentation/iw#Modifying_transmit_bitrates Example usage: iw phy phy0 interface add moni0 type monitor ip link set dev moni0 up iw dev moni0 set channel 36 HT40+ iw set bitrates mcs-5 4 echo 10 > /sys/kernel/debug/ieee80211/phy0/ath9k/tx99_power echo 1 > /sys/kernel/debug/ieee80211/phy0/ath9k/tx99 Signed-off-by: Rajkumar Manoharan <[email protected]> Signed-off-by: Luis R.

2013-10-18rt2800usb: slow down TX status pollingStanislaw Gruszka1-4/+8
Polling TX statuses too frequently has two negative effects. First is randomly peek CPU usage, causing overall system functioning delays. Second bad effect is that device is not able to fill TX statuses in H/W register on some workloads and we get lot of timeouts like below: ieee80211 phy4: rt2800usb_entry_txstatus_timeout: Warning - TX status timeout for entry 7 in queue 2 ieee80211 phy4: rt2800usb_entry_txstatus_timeout: Warning - TX status timeout for entry 7 in queue 2 ieee80211 phy4: rt2800usb_txdone: Warning - Got TX status for an empty queue 2, dropping This not only cause flood of messages in dmesg, but also bad throughput, since rate scaling algorithm can not work optimally. In the future, we should probably make polling interval be adjusted automatically, but for now just increase values, this make mentioned problems gone.

2013-10-18ath5k: fix regression in tx status processingFelix Fietkau1-3/+3
The regression was introduced in the following commit: 0967e01e8e713ed2982fb4eba8ba13794e9a6e89 "ath5k: make use of the new rate control API" ath5k_tx_frame_completed saves the intended per-rate retry counts before they are cleared by ieee80211_tx_info_clear_status, however at this point the information in info->status.rates is incomplete. This causes significant throughput degradation and excessive packet loss on links where high bit rates don't work properly. Move the copy from bf->rates a few lines up to ensure that the saved retry counts are updated, and that they are really cleared in info->status.rates after the call to ieee80211_tx_info_clear_status.
