2012-10-29ath9k_hw: Fix max rx rate drop for AR9565Rajkumar Manoharan
Whenever i_coff of IQ calibration is too high, AR9565 drops max rx rate to MCS4. Skipping IQ update at this time can avoid this problem for AR9565. Signed-off-by: Rajkumar Manoharan <rmanohar@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2012-10-29ath9k_hw: Fix frequent BT rx recoveryRajkumar Manoharan
While resuming from S3, BT host issues HCI reset command and it causes BT firmware to busy with security key calculation. At this movement, WLAN detects MCI hardware error of MCI_CONT_INFO_TIMEOUT and then it starts the recovery sequence repeatedly. Too many recovery sequences would exhaust the BT kernel message pool. This patch imposes a duration between consecutive BT recovery procedure. Thus it solves BT firmware panic issue reported in AR9565.

2012-10-29ath9k: adjust WLAN and BT concurrent transmissionRajkumar Manoharan
The simulataneous transmission of both WLAN and BT might cause increase in power levels. To avoid regulatory violation, WLAN tx power will be adjusted according to BT power index based on avaliability of BT scheduling messages. WLAN tx power reduction might affect its performance. So WLAN tx power is only be lowered when the signal strength is good enough. Otherwise concurrent tx will be disabled and WLAN uses it default power levels. Also concurrent tx is disabled whenever WLAN is moving to off-channel which might be used by BT. Signed-off-by: Rajkumar Manoharan <rmanohar@qca.qualcomm.com> Signed-off-by: John W.

This feature enables both WLAN and BT can transmit simultaneously by setting WLAN and BT to equal priorities. Whenever both are transmitting, it might violate regulatory power limits. To avoid regulatory violation, WLAN tx power will be adjusted according to BT power index based on avaliability of BT scheduling message. If the combined power exceeds threshold, BT transmission will be held off. Signed-off-by: Rajkumar Manoharan <rmanohar@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2012-10-29ath9k: Ensure we set FTP_STOMP_LOW weight when WLAN is idleMohammed Shafi Shajakhan
When WLAN is idle ensure we downgrade to FTP_STOMP_LOW weight (from STOMP_LOW) to provide more bandwidth for BT FTP profile. WLAN's idleness can be estimated by taking into account of the rx data packets and just ignore beacons, qos nullfunc etc. Also update bt_wait_time even if the chip is in NETWORK SLEEP mode.

2012-10-19ath9k: perform ANI cycle in idle stateRajkumar Manoharan
As of now the ANI cycle is executed only when the chip is awake. On idle state case, the station wakes up from network sleep for beacon reception. Since most of the time, ANI cycle is not syncing with beacon wakeup, ANI cycle is ignored. Approx 5 mins once, the calibration is performed. This could affect the connection stability when the station is idle for long. Even though the OFDM and CCK phy error rates are too high, ANI is unable to tune its immunity level as quick enough due to rare execution. Here the experiment shows that OFDM and CCK levels are at default even on higher phy error rate. listenTime=44 OFDM:3 errs=121977/s CCK:2 errs=440818/s ofdm_turn=1 This change ensures that ANI calibration will be exectued atleast once for every 10 seconds. The below result shows improvements and immunity levels are adopted quick enough. listenTime=557 OFDM:4 errs=752/s CCK:4 errs=125/s ofdm_turn=0 Signed-off-by: Rajkumar Manoharan <rmanohar@qca.qualcomm.com> Signed-off-by: John W.

2012-10-19carl9170: handle traps from firmware loaderChristian Lamparter
This patch changes the way the driver deals with command responses and traps which are sent through the special interrupt input endpoint 3. While the carl9170 firmware does not use this endpoint for command responses or traps, the firmware loader on the device does. It uses it to notify the host about 'watchdog triggered' in case the firmware/hardware has crashed. Note: Even without this patch, the driver is still able to detect the mishap and reset the device. But previously it did that because the trap event caused an out-of-order message sequence number error, which also triggered a reset.

2012-10-19orinoco_usb: clean up some signedness issuesDan Carpenter
In ezusb_read_ltv() we had a comparison "(bufsize < 0)" which was never true because bufsize was unsigned. I looked at the implications of that. If we passed a negative number to ezusb_access_ltv() then it would be used as the size parameter of the memcpy() because that function uses min_t(int, exp_len, ans_size). But fortunately when I looked at the callers, bufsize is not controlled by the user and it's never negative. So these signedness mistakes have no impact. I removed the always false check from ezusb_read_ltv() and I changed the types in ezusb_access_ltv() and made the variables unsigned.
