ff9bd2d8d9 ath9k_hw: Handle AR_INTR_SYNC_HOST1_(FATAL|PERR) on AR9003
Interrupts with the sync_cause AR_INTR_SYNC_HOST1_FATAL and
AR_INTR_SYNC_HOST1_PERR have to be handled using a chip reset. Otherwise a
interrupt storm with unhandled interrupts will cause a hang or crash of the
machine.

06bb123e59 brcmfmac: remove brcmf_read_prof() function
The function brcmf_read_prof() provided access to fields
with brcmf_cfg80211_profile structure using a field id,
but the calling function can easily access that structure
directly. This patch removes the function.

The low-level driver part interfaces with wl_cfg80211 part using
brcmf_cfg80211_dev structure as handle. As brcmf_cfg80211_priv
is defined in interface it is more efficient to use that as handle
in function calls.

7bff9c974e mwifiex: send firmware initialization commands synchronously
The driver will send some commands to firmware during the
initialization. Currently these commands are sent asynchronously,
which means that we firstly insert all of them to a pre-allocated
command queue, and then start to process them one by one. The
command queue will soon be exhausted if we keep adding new
initialization commands.

This issue can be resolved by sending initialization commands
synchronously because each command is consumed and the buffer is
recycled before queuing next command.

a549459c96 ath9k: Fix rx filtering issue for older chips
We need to have the promiscuous mode enabled for older
chipsets so that the olderchips hardware does not
filters out some valid/necessary frames that need
to be sent to mac80211. Fix this by enabling promiscus
mode for all the chipsets whose macversion <= AR9160
chipsets. This should fix
https://bugzilla.kernel.org/show_bug.cgi?id=45591

shafi: made the fix generic by having the frame filtering
disabled for chipsets older than AR9280.

af390f4dd3 wlcore: protect wlcore_op_set_key with mutex
wlcore_op_set_key() calls wl18xx_set_key(),
which in turn executes some of his function
calls without acquiring wl->mutex and making
sure the fw is awake.

Adding mutex_lock()/ps_elp_wakeup() calls is
not enough, as wl18xx_set_key() calls
wl1271_tx_flush() which can't be called while
the mutex is taken.

Add the required calls to wlcore_op_set_key,
but limit the queues_stop and flushing
to the only encryption types in which
a spare block might be needed (GEM and TKIP).

ab2c4f37dc wlcore: decrease elp timeout
The current elp timeout (the same as the dynamic
ps timeout - 1500ms) is too high. Usually,
wl1271_ps_elp_sleep() get called right after tx/rx,
which is fine, but some command might get sent
even when there is no traffic (e.g. ht changes
triggered by beacon frames), and leaving the
device awake for 1500ms in this case is redundant.

Use a timeout of 30ms.
The fw won't enter elp anyway before the dynamic-ps
timeout was expired as well (and it entered ps
successfully).

6f8d6b20bb wlcore: Load the NVS file asynchronously
The NVS file is loaded by the device's probe callback with the help of
request_firmware(). Since request_firmware() relies on udevd, the
modules cannot be loaded before hotplug events are handled.

Fix this by loading the NVS file asynchronously and continue
initialization only after the firmware request is over.

d556023895 wlcore: Allow memory access when the FW crashes
When the no_recovery flag is used, the recovery work will not restart
the FW and the state will not be set to 'on'. To enable post-mortem
analysis, allow memory access in the 'restarting' state.

Also, since the FW might not be operational, don't fail the read/write
operations if elp_wakeup fails.

001e39a8ef wlcore: use dynamic keep-alive template ids
Currently, all the (station) roles use the same
keep-alive template id (0). However, the klv
template ids shouldn't be shared by different
roles.

Implement a simple klv_templates bitmap, and let
each role allocate its own klv template id on
role initialization.

4137c17c8c wlcore: invalidate keep-alive template on disconnection
Previously, invalidation of the keep-alive template was
done when going idle. However, while removing the
idle-handling we didn't move the keep-alive template
invalidation to another place.

This finally resulted in fw error when trying to use
the keep-alive template by another role.

(Note that we still have an error here - each role
should have its unique keep-alive template id, while
currently they all use CMD_TEMPL_KLV_IDX_NULL_DATA (0).
This only works now because we don't support concurrent
connected stations yet)

792a58a872 wlcore: Don't recover during boot
While recursive recovery is avoided during shutdown, a new recovery may
be queued when the FW boots. The recovery work will then try to stop an
already stopped hardware, which will most likely result in a kernel
panic.

Fix this by verifying that wl->state is on before queueing a new
recovery.

e166de556f wl18xx: number_of_assembled_ant5 indicates if A band is enabled
Use number_of_assembled_ant5 phy param to indicate if A band is enabled:
if number_of_assembled_ant5 != 0 then it is enabled otherwise it is
disabled.

This aligns with phy implementation that uses this param both to indicate
if band is active and the number of antennas.

This parameter replaces enable_11a module param that was removed.

User-Space applications can use wlconf and/or INI files to disable A band
using this parameter.
