* ath9k_hw: remove unnecessary parts of the AR9380 SREV checkFelix Fietkau2011-04-121-3/+1
| | | | | | | | | Older versions have not been sold and the driver does not explicitly check for them anyway, so we can simply ignore the macRev here. Reduces ath9k_hw size on mips by more than 2 KB.

* ath9k_hw: Fix instable target power control b/w CCK/OFDMRajkumar Manoharan2011-04-123-1/+37
| | | | | | | | | | | | | | | | | | | | | The problem is that when the attenuation is increased, the rate will start to drop from MCS7 -> MCS6, and finally will see MCS1 -> CCK_11Mbps. When the rate is changed b/w CCK and OFDM, it will use register desired_scale to calculate how much tx gain need to change. The output power with the same tx gain for CCK and OFDM modulated signals are different. This difference is constant for AR9280 but not AR9285/AR9271. It has different PA architecture a constant. So it should be calibrated against this PA characteristic. The driver has to read the calibrated values from EEPROM and set the tx power registers accordingly.

* mac80211: Check for queued frames before entering power save.Vivek Natarajan2011-04-124-8/+46
| | | | | | | | | | | | | | | In a highly noisy environment, the tx rate of the driver drops and the application slows down since it has not yet received ACKs for the frames already queued in the hardware. Since this ACK may take more than 100ms, stopping the dev queues for entering PS at this stage breaks applications, WMM test cases in my testing. If there are frames already pending in the tx queue, postponing the PS logic helps to avoid redundant queue stops. When power save is enabled by default and in a noisy environment, this API certainly helps in improving the average throughput.

* iwlagn: clean up & autodetect statisticsJohannes Berg2011-04-0813-376/+243
| | | | | | | | | | | | | | | | | | | | | | | | | | | | There's no need to keep both normal and BT statistics versions around all the time in memory when we only use a subset of both. So keep only the subsets that we need in memory, depending on the debug config). Also, in doing so, we can remove all the calls to iwl_bt_statistics() in the driver as we'll just access the copied statistics now. Finally, also remove this call from the one place where it might still be needed and automatically detect what kind of statistics the device is sending based on their size. This way, we don't need to keep track of which devices do what any more, which is good since this is subject to change based on the ucode version (as some ucode even for non-BT devices will in fact use BT statistics). Warn upon encountering a statistics command from the ucode that isn't known, so we will find such issues earlier in the future.

* iwlagn: fix radar frame rejectionGaren Tamrazian2011-04-087-8/+74
| | | | | | | | | | | | | | | | | | The microcode may sometimes reject TX frames when on a radar channel even after we associated as it clears information during association and needs to receive a new beacon before allowing that channel again. This manifests itself as a TX status value of TX_STATUS_FAIL_PASSIVE_NO_RX. So in this case, stop the corresponding queue and give the frame back to mac80211 for retransmission. We start the queue again when a beacon from the AP is received which will make the regulatory enforcement in the device allow transmitting again.
