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. The change is to return success in this scenario, because firmware reset will anyhow shutdown the AP.

2015-01-29wil6210: fix timing of netif_carrier_on indicationDedy Lansky
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. The fix is to indicate netif_carrier_on earlier: for STA, indicate netif_carrier_on when association starts. for AP/PCP, indicate netif_carrier_on upon starting AP/PCP.

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. The compiler error is as following: drivers/net/wireless/ath/ath9k/ath9k_htc.o:(.data+0x47c): multiple definition of `led_blink' drivers/net/wireless/ath/ath9k/ath9k.o:(.bss+0x20): first defined here Fixes: 3a939a671225 ("ath9k_htc: Add a module parameter to disable blink") Reported-by: kbuild test robot <fengguang.wu@intel.com> Signed-off-by: Hong Xu <hong@topbug.net> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

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. Thus, two wcn36xx devices cannot do a-mpdu between themselves since they both wait for the other to go first. Fix this by starting a BA session after a few QoS data frames have been sent to a STA.

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. Also, passing the whole skb instead of just the header pointer to the set_tx_data function paves the way for using its fields for ampdu setup inside set_tx_data().

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. However, we can sidestep the issue by letting the hardware generate the sequence numbers for QoS frames, as is done in prima, so do that.

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.

2015-01-15cfg80211: 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>

2015-01-15wil6210: relax spinlocks in rx reorderVladimir Kondratiev
In the Rx reorder mechanism, nothing is done in the interrupt context, so there is no need to use 'irq' flavors of spinlock. Rx done in NAPI context (tasklet), other manipulations - in the thread context. Having interrupts enabled makes it better for the OS in general. Besides, if enslaved under bonding, bridge or team driver, Rx won't work with interrupts disabled.

2015-01-15wil6210: add advanced interrupt moderationVladimir Kondratiev
Add advanced interrupt moderation support available since "Sparrow B0". Legacy interrupt moderation used only one counter to moderate tx, rx, and misc interrupts. Advanced interrupt moderation bypasses misc, and handles separately tx and rx interrupts. In addition it has two timers for each interrupt type. Max burst duration timer which defines how long to postpone interrupt after first event (receive event for rx and tx complete event for tx), and interframe timeout which defines how to determine the end of the burst and issue interrupt even if the first timer still pending. Capabilities flags in wil_priv is set on initialization according to HW. The rest of the code checks for advanced interrupt capability bit in capabilities flags field. Debugfs is split accordingly: "legacy" interrupt moderation remains unchanged, new debugs files added for advanced interrupt moderation support. Module params are aligned to support advanced interrupt moderation (tx & rx). When not available (for legacy interrupt moderation) will use only rx configuration; Tx configuration will be ignored in this case.

Eventually, it gets event confirming BACK agreement - WMI_BA_STATUS_EVENTID with negotiated parameters. On this event, update Tx vring data (struct vring_tx_data) and display BACK parameters on debugfs - recipient Rx side (recipient) firmware informs driver about ADDBA with WMI_RCP_ADDBA_REQ_EVENTID, driver process it in service work queue wq_service. It adjusts parameters and sends response with WMI_RCP_ADDBA_RESP_CMDID, and final confirmation provided by firmware with WMI_ADDBA_RESP_SENT_EVENTID.
