2014-03-28ath10k: add the Rx rate in FW statsBen Greear
FW stats does provide the Rx rate information. Add this. Tested with firmware 10x firmware. Increase buffer size so more peers can be shown. Signed-off-by: Chun-Yeow Yeoh <yeohchunyeow@gmail.com> Signed-off-by: Ben Greear <greearb@candelatech.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2014-03-28ath10k: fix getting stats from firmwareBen Greear
Tested on 10.x firmware, and others report it at least makes older firmware no more broken than it already was. Signed-off-by: Ben Greear <greearb@candelatech.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2014-03-28ath10k: update wal_dbg_tx_stats structure with missing parameter.Bartosz Markowski
The filed has been missing (missmatched with FW ABI) since 999.999.0.629 firmware release. It's very imporatant to keep these structs up to date with FW, due to the arithmetic we use while read the fw_stats.

2014-03-28ath10k: deinit copy engine before resettingMichal Kazior
Since copy engine allocation has been revised the ath10k_pci_ce_deinit() now simply zeroes copy engine registers. It's probably a good idea to do that before reseting for a more graceful device reset. Before ath10k_pci_ce_deinit() freed copy engine ringbuffer memory so it was required to call it after resetting. Otherwise it was possible for device to access unmapped/freed copy engine ringbuffer memory. Signed-off-by: Michal Kazior <michal.kazior@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2014-03-28ath10k: split ce initialization and allocationMichal Kazior
Definitions by which copy engine structure are allocated do not change so it doesn't make much sense to re-create those structures each time device is booted (e.g. due to firmware recovery). This should decrease chance of memory allocation failures. While at it remove per_transfer_context pointer indirection. The array has been trailing the copy engine ringbuffer structure anyway. This also saves pointer size worth of bytes for each copy engine ringbuffer.

2014-03-28ath10k: convert pci_alloc_consistent() to dma_alloc_coherent()Michal Kazior
This allows to use GFP_KERNEL allocation. This should decrease chance of allocation failure, e.g. during firmware recovery. Reported-By: Avery Pennarun <apenwarr@gmail.com> Signed-off-by: Michal Kazior <michal.kazior@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

2014-03-28ath10k: fix name of target_ps module parameterKalle Valo
The parameter name was ath10k_target_ps, but actually it should be just target_ps. Module parameter names should not use the ath10k_ prefix. Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2014-03-28ath10k: add module parameter to disable cold resetKalle Valo

2014-03-27rtl8180: rationalize TX queuesAndrea Merello
On currently supported HW there are four TX queues (three for normal packets and one for beacons). The driver uses just one TX queue, and declare to mac80211 to support just one queue, but it allocates coherent memory for all queues. Furthermore the TX is code is written assumimg four queues exists, and even if we decide to enable more queues in future, its mapping rule to mac80211 is fixed. This means we have memory waste on rtl8180/rtl8185, and we have also not enough flexibility to add support for boards (rtl8187se) that will use more queues. This patch changes things in order to allocate coherent memory only for the queues effectively used and it make it possible to specify how to map hardware queues on mac80211 queues, that will be used by rtl8187se code as soon it will be merged. Note: even if the beacon queue is currently unused, this should change, so I kept it. Signed-off-by: Andrea Merello <andrea.merello@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

Currently during heavy traffic we could have: - 10 packets with START_VALID - correct RSSI and RATES - 10 packets with END_VALID - 10 packets with START_VALID - correct RSSI and RATES - 10 packets with END_VALID ...
