2013-03-27brcmsmac: remove brcms_bss_cfg->BSSHauke Mehrtens
This was a read only member. The checks using BSS are replaced by better fitting checks of the new type member. The change in brcms_c_tbtt() was based on code from b43, in brcms_c_ps_allowed() the same happens with BSS being true or false, beaconing and probe responses are just needed in ap mode.

2013-03-27mwifiex: use fw_status register to wake up PCIe cardAvinash Patil
FW can be woken up even by accessing device registers; we need not explicitily enable interrupts for doing this. Future PCIe devices will not be woken up by writing to host registers. This patch enables driver to wake up device by reading FW status register. Also devices with sleep cookie enabled need some more time before proceeding with processing. Handle this by adding a delay loop. Signed-off-by: Avinash Patil <patila@marvell.com> Signed-off-by: Bing Zhao <bzhao@marvell.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2013-03-27b43: N-PHY: use more bits for offset in RSSI calibrationRafał Miłecki
When calculating "offset" for final RSSI calibration we're using numbers bigger than s8 can hold. We have for example: offset[j] = 232 - poll_results[j]; formula. If poll_results[j] is small enough (it usually is) we treat number's bit as a sign bit. For example 232 - 1 becomes: 0xE8 - 0x1 = 0xE7, which is not 231 but -25. This code was introduced in e0c9a0219a8f542e3946fe972a68aacf8c3f906c and caused stability regression on some cards, for ex. BCM4322.

2013-03-27b43: A fix for DMA transmission sequence errorsIestyn C. Elfick
Intermittently, b43 will report "Out of order TX status report on DMA ring". When this happens, the driver must be reset before communication can resume. The cause of the problem is believed to be an error in the closed-source firmware; however, all versions of the firmware are affected. This change uses the observation that the expected status is always 2 less than the observed value, and supplies a fake status report to skip one header/data pair. Not all devices suffer from this problem, but it can occur several times per second under heavy load. As each occurence kills the unmodified driver, this patch makes if possible for the affected devices to function. The patch logs only the first instance of the reset operation to prevent spamming the logs.

2013-03-27b43: N-PHY: increase initial value of "mind" in RSSI calibrationRafał Miłecki
We're using "mind" variable to find the VCM that got the best polling results. For each VCM we calculte "currd" which is compared to the "mind". For PHY rev3+ "currd" gets values around 14k-40k. Looking for a value smaller than 40 makes no sense, so increase the initial value. This fixes a regression introduced in 3.4 by commit: e0c9a0219a8f542e3946fe972a68aacf8c3f906c (my BCM4322 performance dropped from 18,4Mb/s to 9,26Mb/s) Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Cc: stable@vger.kernel.org Signed-off-by: John W.

2013-03-25mwifiex: reset skb->data after processing PCIe sleep confirm cmd resposeAvinash Patil
This patch is a bug fix for an issue wherein power save was not working for PCIe. This happens because for processing power save sleep confirm command we pull skb so that skb->data points ahead of interface header. We use same skb to get other cmda responses as well. So if we don't push skb after processing cmd response, it results into reduction in skb->len and finally skb->len reaches zero. This causes failure in processing sleep command response. Fix this by pushing skb by INTF_HEADER_LEN at the end of command response processing.
