2015-01-29wil6210: tuning rings sizeVladimir Shulman
Tuning rings size for performance optimization. Increasing Tx ring size, allows buffering more packets for HW, thus eliminating idle periods which were observed with smaller ring at high throughput, because HW was fetching packets faster than driver was filling them into the TX ring. Rx ring was similarly increased to avoid same problems in Rx.

2015-01-29wil6210: ignore firmware failure to gracefully stop APDedy Lansky
upon cfg80211_stop_ap, a graceful AP shutdown is requested from firmware followed by firmware reset. In case graceful request failed, error was returned to cfg80211.

netif_carrier_on indication was too late. In case Rx packet received before netif_carrier_on indication, upper layers could not send Tx packet back.

2015-01-27ath9k and ath9k_htc: rename variable "led_blink"Hong Xu
ath9k and ath9k_htc use the variable name "led_blink" to indicate whether the module parameter "blink" is on. This name is easy to conflict with other variables, and has caused a compiler error found by kbuild test bot.

2015-01-27ath10k: fix dtim period with beacon templatesMichal Kazior
Firmware supporting beacon templates (i.e. wmi-tlv for qca6174) doesn't implicitly take dtim period from the template. Instead it requires vdev param to be set accordingly.

The QCA6174 in combination with new wmi-tlv firmware is capable of multi-channel, beamforming, tdls and other features.

2015-01-27ath10k: add support for qca6174 Rx descriptorsMichal Kazior
The QCA6174 chip has an extra 4 bytes in rx_ppdu_end structure which is used in htt_rx_desc and HTT Rx ring offset setup. This is necessary for correct Rx for QCA6174 (otherwise Rx descriptors are overwritten and corrupted). This means QCA988X will have an extra 4 byte padding in Rx descriptor layout which is harmless.

New firmware and firmware (qca6174 hw3.0+ and fw 266+) are capable of full aggregation rx reordering. If it's enabled then Rx is handled via a new, separate htt event.

2015-01-23wcn36xx: initiate TX BA sessionsBob Copeland
Currently, wcn36xx only asks for a TX BA session if it has already established one for RX.

2015-01-23wcn36xx: move set_tx_pdu inside set_tx_data/mgmtBob Copeland
The pdu is part of the buffer descriptor, so it makes sense that one function would fill both.

2015-01-23wcn36xx: let device generate qos seq numbersBob Copeland
wcn36xx currently sends an incorrect sequence number into the BA session setup firmware command: it should be saving or updating the ssn in the TX_START ampdu_action callback instead of waiting until TX_OPERATIONAL.

2015-01-23wcn36xx: use !! when assigning int as a booleanBob Copeland
bd->tx_comp is a single bit in a bitfield, so assigning "info->flags & IEEE80211_TX_CTL_REQ_TX_STATUS" only happens to work because TX_STATUS is defined to BIT(0); if it were any other bit this assignment would fail.

2015-01-19ath9k: fix race condition in irq processing during hardware resetFelix Fietkau
To fix invalid hardware accesses, the commit 872b5d814f99 ("ath9k: do not access hardware on IRQs during reset") made the irq handler ignore interrupts emitted after queueing a hardware reset (which disables the IRQ). This left a small time window for the IRQ to get re-enabled by the tasklet, which caused IRQ storms. Instead of returning IRQ_NONE when ATH_OP_HW_RESET is set, disable the IRQ entirely for the duration of the reset.

2015-01-15cfg80211: change bandwidth reporting to explicit fieldJohannes Berg
For some reason, we made the bandwidth separate flags, which is rather confusing - a single rate cannot have different bandwidths at the same time. Change this to no longer be flags but use a separate field for the bandwidth ('bw') instead. While at it, add support for 5 and 10 MHz rates - these are reported as regular legacy rates with their real bitrate, but tagged as 5/10 now to make it easier to distinguish them. In the nl80211 API, the flags are preserved, but the code now can also clearly only set a single one of the flags. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
