Start/stop TX queue is controlled by TX queue "used" counter.
It is incremented while WRBs are posted to TX queue and
decremented when TX completions are received. This counter was
getting decremented before HW is informed about processing of TX
completions. As used counter is decremented, transmit function
posts new WRBs and creates completion queue full scenario in HW.

The structure definition is
struct mwifiex_opt_sleep_confirm_buffer {
u8 hdr[4];
struct mwifiex_opt_sleep_confirm ps_cfm_sleep;
} __packed;
For sleep_confirm command we already reserve 4 bytes (using skb_reserve())
for an interface header. It will be filled later by interface specific code.
We don't need "hdr[4]" element in above structure. So we can use
"struct mwifiex_opt_sleep_confirm" directly instead of
"struct mwifiex_opt_sleep_confirm_buffer".

In driver rtlwifi, efuse_read() places two relatively large arrays on the
stack - a 1D u8 array of size 128, and a 2D array of u16 with 128 * 4 elements.
With driver rtl8192de, the sizes will be 256 and 256 * 4 respectively. As that
will make the 2D array be 2048 bytes, I have changed the code to use kmalloc to
allocate the space.

The function iwl_is_any_associated() was intended
to check both contexts, but due to an oversight
it only checks the BSS context. This leads to a
problem with scanning since the passive dwell
time isn't restricted appropriately and a scan
that includes passive channels will never finish
if only the PAN context is associated since the
default dwell time of 120ms won't fit into the
normal 100 TU DTIM interval.
Fix the function by using for_each_context() and
also reorganise the other functions a bit to take
advantage of each other making the code easier to
read.

The assumsion is that while processing ath9k tasklet,
interrupts were already disabled and it will be enabled
at the completion of ath9k tasklet. But whenever TSFOOR is raised,
the driver configures the beacon timers after having received a
beacon frame from the AP which inturn enables the interrupts.

We occasionally see list corruption using libertas.
While we haven't been able to diagnose this precisely, we have spotted
a possible cause: cmdpendingq is generally modified with driver_lock
held. However, there are a couple of points where this is not the case.
Fix up those operations to execute under the lock, it seems like
the correct thing to do and will hopefully improve the situation.

We should not switch to non-IBSS channels when working in IBSS mode,
otherwise there are microcode errors, and after some time system
crashes.
This bug is only observable when software scan is used in IBSS mode,
so should be considered as regression after:

iwlwifi: remove IBSS channel sanity check
That commit claim that mac80211 will not use non-IBSS channel in IBSS

mac80211, but that will require more work, so better to apply that patch
temporally, and provide proper mac80211 fix latter.

during suspend/S3 state drv_flush is called from mac80211 irrespective of
interface count. In ath9k we queue a work in ath9k_flush which we expect
to be cancelled in the drv_stop call back. during suspend process mac80211
calls drv_stop only when the interface count(local->count) is non-zero.
unfortunately when the network manager is enabled, drv_flush is called
while drv_stop is not called as local->count reaches '0'.
So fix this by simply checking for the device presence in the
drv_flush call back in the driver before queueing work or anything else.
