- ath9k: Fix crash in MCC mode
-
- When a channel context is removed, the hw_queue_base
- is set to -1, this will result in a panic because
- ath9k_chanctx_stop_queues() can be called on an interface
- that is not assigned to any context yet - for example,
- when trying to scan.
-
- Fix this issue by setting the hw_queue_base to zero
- when a channel context is removed.

- ath9k: Fix flushing in MCC mode
-
- When we are attempting to switch to a new
- channel context, the TX queues are flushed, but
- the mac80211 queues are not stopped and traffic
- can still come down to the driver.
-
- This patch fixes it by stopping the queues
- assigned to the current context/vif before
- trying to flush.

-
- ath9k: Fix queue handling for channel contexts
-
- When a full chip reset is done, all the queues
- across all VIFs are stopped, but if MCC is enabled,
- only the queues of the current context is awakened,
- when we complete the reset.
-
- This results in unfairness for the inactive context.
- Since frames are queued internally in the driver if
- there is a context mismatch, we can awaken all the
- queues when coming out of a reset.
-
- The VIF-specific queues are still used in flow control,
- to ensure fairness when traffic is high.

- chan_lock is not required for checking if
- we are in the middle of a HW reset, so do it
- early. This also removes the small window

- ath9k_htc: avoid kernel panic in ath9k_hw_reset
-
- hw pointer of ath_hw is not assigned to proper value
- in function ath9k_hw_reset what finally causes kernel panic.
- This can be solved by proper initialization of ath_hw in
- ath9k_init_priv.

- ath9k: fix getting tx duration for dynack
-
- On AR9003, tx control and tx status are in separate descriptor rings.
- Tx duration is extracted from the tx control descriptor data, which
- ar9003_hw_proc_txdesc cannot access.
-
- Fix getting the duration by adding a separate callback for it.

- ath9k_hw: fix PLL clock initialization for newer SoC
-
- On AR934x and newer SoC devices, the layout of the AR_RTC_PLL_CONTROL
- register changed. This currently breaks at least 5/10 MHz operation.
- AR933x uses the old layout.
-
- It might also have been causing other stability issues because of the
- different location of the PLL_BYPASS bit which needs to be set during
- PLL clock initialization.
-
- This patch also removes more instances of hardcoded register values in
- favor of properly computed ones with the PLL_BYPASS bit added.

- ath9k_hw: reduce ANI spur immunity setting on HT40 extension channel
-
- The cycpwr_thr1 value needs to be lower on the extension channel than on
- the control channel, similar to how the register settings are programmed
- in the initvals.
-
- Also drop the unnecessary check for HT40 - this register can always be
- written. This patch has been reported to improve HT40 stability and
- throughput in some environments.

- ath9k_hw: disable hardware ad-hoc flag on ar934x rev 3
-
- On AR934x rev 3, settin the ad-hoc flag completely messes up hardware
- state - beacons get stuck, almost no packets make it out, hardware is
- constantly reset.
-
- When leaving out that flag and setting up the hw like in AP mode, TSF
- timers won't be automatically synced, but at least the rest works.
-
- AR934x rev 2 and older are not affected by this bug

+Subject: [PATCH] ath9k: Enable multi-channel properly
+
+In MCC mode, currently the decision to enable
+the multi-channel state machine is done
+based on the association status if one of
+the interfaces assigned to a context is in
+station mode.
+
+This allows the driver to switch to the other
+context before the current station is able to
+complete the 4-way handshake in case it is
+required and this causes problems.
+
+Instead, enable multi-channel mode when the
+station moves to the authorized state. This
+disallows an early switch to the other channel.

+Subject: [PATCH] ath9k: Set ATH_OP_HW_RESET before HW reset
+
+When a HW reset is done, the interrupt tasklet is
+disabled before ISRs are disabled in the HW. This
+allows a small window where the HW can still generate
+interrupts. Since the tasklet is disabled and not killed,
+it is not scheduled but deferred for execution at a later
+time.
+
+This happens because ATH_OP_HW_RESET is not set when ath_reset()
+is called. When the hw_reset_work workqueue is used, this
+problem doesn't arise because ATH_OP_HW_RESET is set
+and the ISR bails out.
+
+Set ATH_OP_HW_RESET properly in ath_reset() to avoid
+this race - all the ath_reset_internal() callers have
+been converted to use ath_reset() in the previous patch.

+
+The timeout value for flushing the TX queues
+is hardcoded at 200ms right now. Use a channel
+context-specific value instead to allow adjustments

+Subject: [PATCH] ath9k: Fix MCC flush timeout
+
+In MCC mode, the duration for a channel context
+is half the beacon interval and having a large
+flush timeout will adversely affect GO operation,
+since the default value of 200ms will overshoot
+the advertised NoA absence duration.
+
+The scheduler initiates a channel context switch
+only when the slot duration for the current
+context expires, so there is no possibility of
+having a fixed timeout for flush.
+
+Since the channel_switch_time is added to the
+absence duration when the GO sets up the NoA
+attribute, this is the maximum time that we
+have to flush the TX queues. The duration is very
+small, but we don't have a choice in MCC mode.

+Subject: [PATCH] ath9k: Check for pending frames properly
+
+Pending frames in the driver can be present
+either in the HW queues or SW. ath9k_has_pending_frames()
+currently checks for the HW queues first and then
+checks if any ACs are queued in the driver.
+
+In MCC mode, we need to check the HW queues alone, since
+the SW queues are just marked as 'stopped' - they will
+be processed in the next context switch. But since we
+don't differentiate this now, mention whether we want
+to check if there are frames in the SW queues.
+
+* The flush() callback checks both HW and SW queues.
+* The tx_frames_pending() callback does the same.
+* The call to __ath9k_flush() in MCC mode checks HW queues alone.

+Subject: [PATCH] ath9k: Fix RoC expiration
+
+mac80211 has to be notified when a RoC period
+expires in the driver. In MCC mode, since the
+offchannel/RoC timer is set with the requested
+duration, ieee80211_remain_on_channel_expired() needs
+to be called when the timer expires.
+
+But, currently it is done after we move back to
+the operating channel. This is incorrect - fix this
+by calling ieee80211_remain_on_channel_expired() when
+the RoC timer expires and in ath_roc_complete() when

+The flush timeout in MCC mode is very small, since

+
+Since the SW queues are also emptied in the mac80211 flush()

+Subject: [PATCH] ath9k: Do not start BA when scanning
+
+mac80211 currently has a race which can be hit
+with this sequence:
+
+* Start a scan operation.
+* TX BA is initiated by ieee80211_start_tx_ba_session().
+* Driver sets up internal state and calls
+ ieee80211_start_tx_ba_cb_irqsafe().
+* mac80211 adds a packet to sdata->skb_queue with
+ type IEEE80211_SDATA_QUEUE_AGG_START.
+* ieee80211_iface_work() doesn't process the
+ packet because scan is in progress.
+* ADDBA response timer expires and the sta/tid is
+ torn down.
+* Driver receives BA stop notification and calls
+ ieee80211_stop_tx_ba_cb_irqsafe().
+* This is also added to the queue by mac80211.
+* Now, scan finishes.
+
+At this point, the queued up packets might be processed
+if some other operation schedules the sdata work. Since
+the tids have been cleaned up already, warnings are hit.
+
+If this doesn't happen, the packets are left in the queue
+until the interface is torn down.
+
+Since initiating a BA session when scan is in progress
+leads to flaky connections, especially in MCC mode, we
+can drop the TX BA request. This improves connectivity
+with legacy clients in MCC mode.

+Subject: [PATCH] ath9k: fix processing RXORN interrupts
+
+The "goto chip_reset" is a bit misleading, because it does not actually
+issue a chip reset. Instead it is bypassing processing of other
+interrupts and assumes that the tasklet will issue a chip reset.
+
+In the case of RXORN this does not happen, so bypassing processing of
+other interrupts will simply allow them to fire again. Even if RXORN
+was triggering a reset, it is not critical enough to need the bypass
+here.
