After setting interrupt handler, driver enabled interrupts.
This caused stale (old) HW interrupts to fire before driver is
fully initialized.
The fix is to enable interrupts only when driver is fully initialized
and after FW/HW reset (to prevent any stale interrupts)

The 0-DAY kernel build testing backend reports the following warning:
drivers/net/wireless/rtlwifi/btcoexist/halbtcoutsrc.c:516 halbtc_bitmask_write_1byte()
warn: always true condition '(bit_mask != 4294967295) => (0-255 != u32max)'
This problem was introduced in commit ed364abffd6e19bec67b7ccda8237213b8b37640,
and arises because the caller of halbtc_bitmask_write_1byte() is using a
u8 rather than a u32 for the data.

This reverts commit 09ebb810927a110e4c354beb20308830d108a54b.
ath9k_hw_set_sta_beacon_timers() configures AR_TIM_PERIOD with
the beacon interval. Before this commit, the sleepduration was
never greater than the beacon interval. But now, the behavior
has changed. For example, with an AP that uses a beacon interval of 100:
ath: phy9: next beacon 61128704
ath: phy9: beacon period 204800
ath: phy9: DTIM period 204800
If the sleepduration is calculated based on the listen time, then
the bmiss threshold should also be changed since the HW would
be in sleep state for a longer time, but that is not done currently.
To avoid configuring a higher beacon interval based on the sleepduration,
revert to the original behavior. Power consumption is not a
problem since PS is disabled in ath9k anyway.

Scanning is curently broken when two channel contexts
are active. For example in a P2P-GO/STA setup, the
offchannel timer allows HZ / 10 to elapse before initiating
a switch to the next scan channel from the current operating
channel, which in this case would be the P2P-GO context.
But, the channel context timer might decide to switch
to the STA context when an SWBA comes early and a beacon
is sent out. Since pending offchannel requests are processed
in EVENT_BEACON_PREPARE, this causes inconsistent scanning.
Fix this by making sure that a context switch happens
before processing the pending offchannel request. This
also makes sure that active channel contexts will always
have higher priority than offchannel operations and the
scan sequence looks like this:
p2p-go, sta, p2p-go, offchannel, p2p-go, sta, p2p-go, offchannel,.....
The oper-channel is p2p-go, so the STA context has to
switch to p2p-go again before switching offchannel.

When multiple channel contexts are active, an offchannel
request will not be handled immediately, but will be
queued to be handled later. But, currently, the channel definition
is not copied to the local offchannel state. This
breaks operation like scanning when MCC is active.
Fix this by storing the offchannel parameters properly.

The start time field in the NoA attribute needs to be
updated based on the TSF timer when an absence notification
is sent by the P2P GO. When two channel contexts are active,
continuous, cyclic NoA is announced by setting the count value to 255,
but the start time is updated only once, for one beacon and
the same value is sent in all subsequent beacons, even
though the timestamp keeps moving.
Fix this by removing the check for 'periodic_noa_duration'
and assign the interface's start_time/duration values directly
when there is more than one active context.

If a station interface is already assigned to a context
and is active and a second interface of type AP is added,
then beaconing on the new interface has to be begin only
after the BSS_CHANGED_BEACON_ENABLED flag is sent by mac80211
to the driver.
But, since we issue ATH_CHANCTX_EVENT_ENABLE_MULTICHANNEL as soon
as a new channel context is added, a switch occurs almost immediately
before BSS_CHANGED_BEACON_ENABLED is received. When a HW reset
is done for the new context, beacons are enabled for the
interface since "enable_beacon" in the BSS config maintained
in mac80211 is true - but the driver hasn't been notified yet.
This causes a panic, since the beacon interval is zero for this
interface and ath9k_cmn_beacon_config_ap() doesn't have a safety check.
Fix this panic by checking if the beacon params has been cached
for this context and use the "enable_beacon" flag maintained
locally in the driver. Also, recalculate the summary data
after the beacon params have been cached when BSS_CHANGED_BEACON_ENABLED
is received.

In channel context mode, when a new context is added,
mac80211 issues a bss_info_changed() notfication when
preparing the connection for the new interface/context.
But, this is done prior to the mgd_prepare_tx() call which
is where we switch to the new context. Since the current
context will be different when the earlier bss_info_changed()
is handled, the beacon information for the VIF is not
updated, but discarded since the rules for the current context
disallows it.
In the subsequent association process for the new context/vif,
this becomes a problem because the beacon parameters are invalid.
This causes problems with the TSF timer, causing large jumps.
To fix this, check if the beacon info is being updated for a
different context and if so, allow it without any checks since
we limit the max. interfaces to two anyway.
