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: Process beacons properly
When the current operating channel context has
been marked as ATH_CHANCTX_STATE_FORCE_ACTIVE,
do not process beacons that might be received,
since we have to wait for the station to become
authorized.
Also, since the cached TSF value will be zero
initially do not rearm the timer in this
case when a beacon is received, since it results
in spurious values.

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.

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: Send AUTHORIZED event only for station mode
ATH_CHANCTX_EVENT_AUTHORIZED is required to trigger
the MCC scheduler when a station interface becomes
authorized. But, since the driver gets station state
notifications when the current operating mode is AP
too, make sure that we send ATH_CHANCTX_EVENT_AUTHORIZED
only when the interface is in station mode.

Since both the arguments need to satisfy
the alignment requirements of ether_addr_copy(),
use memcpy() in cases where there will be no
big performance benefit and make sure that
ether_addr_copy() calls use properly aligned
arguments.

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 RoC request is aborted.

Subject: [PATCH] ath9k: Fix HW scan abort
Instead of using ATH_CHANCTX_EVENT_ASSIGN to abort
a HW scan when a new interface becomes active, use the
mgd_prepare_tx() callback. This allows us to make
sure that the GO's channel becomes operational by
using flush_work().

Subject: [PATCH] ath9k: Improve flush() in mcc mode
The flush timeout in MCC mode is very small, since
we are constrained by the time slice for each
channel context, but since only the HW queues are
flushed when switching contexts, it is acceptable.
Since the SW queues are also emptied in the mac80211 flush()
callback, a larger duration is needed. Add an override
argument to __ath9k_flush() and set it when flush()
is called in MCC mode. This allows the driver to
drain both the SW and HW queues.

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.

Subject: [PATCH] ath9k: add support for endian swap of eeprom from
platform data
On some devices (especially little-endian ones), the flash EEPROM data
has a different endian, which needs to be detected.
Add a flag to the platform data to allow overriding that behavior
