dd45b7598f ath6kl: Include match ssid list in scheduled scan
Scheduled scan implementation was only taking probed list into
consideration. The matched list was dropped. This would cause
FW not to report the AP as the list never had that AP's SSID
populated. This was causing long connection time when supplicant
would just issue a wild card SSID in probed list. As a part of
this implementation, ath6kl driver would create a complete list
by taking both probed and matched list and pass it to FW. FW would
probe for the SSID that it needs to and would match against the
relevant SSIDS that is been configured.

8ab5415d6c ath6kl: Use correct max-scan-SSIDs limit
The currently used firmware images support 16 SSIDs in the scan
request (indexes 0..15), so update the host driver to use the same
limit to allow some more SSIDs to be scanned per request. In addition,
change the max-index to max-SSIDs to make it easier to understand the
implementation and fix couple of off-by-one checks that could limit
the maximum number of entries too strictly.

f374057251 ath6kl_sdio: Fix the EAPOL out of order issue
Send the EAPOL and management frames in the same AC_VO queue. The issue
happens when the AP supports QOS, the management frames are sent to AC_VO
queue and EAP frame goes to AC_BE queue. Even though the EAP frame is
queued before the DEAUTH management frame, as they are queued on different
h/w queues, order of delivery between these frames cannot be controlled.

This fixes the connection failure seen in P2P case.

d97c121bb2 ath6kl: Fix 4-way handshake failure in AP and P2P GO mode
RSN capability field of RSN IE which is generated (which is what really
advertised in beacon/probe response) differs from the one generated in
wpa_supplicant. This inconsistency in rsn IE results in 4-way handshake
failure. To fix this, configure rsn capability used in wpa_supplicant
in firmware using a new wmi command, WMI_SET_IE_CMDID. There is a bit
(ATH6KL_FW_CAPABILITY_RSN_CAP_OVERRIDE) in fw_capabilities to advertise

081c7a84e9 ath6kl: Wait for host sleep mode cmd processed event during WOW suspend
For every WMI_SET_HOST_SLEEP_MODE_CMDID command (send from the host),
the firmware sends WMI_SET_HOST_SLEEP_MODE_CMD_PROCESSED_EVENTID as
an acknowledgement to the host.

In order to being sync with the firmware, the host has to wait for
WMI_SET_HOST_SLEEP_MODE_CMD_PROCESSED_EVENT event before going to
the suspend state. This patch ensures ath6kl_wow_suspend() waits
until it gets this event after sending set host sleep mode command.

This patch adds,
 * New command WMI_SET_HOST_SLEEP_MODE_CMD_PROCESSED_EVENTID in
   WMI event table.
 * New WMI function ath6kl_wmi_host_sleep_mode_cmd_prcd_evt_rx()
   to process the event.
 * New flag HOST_SLEEP_MODE_CMD_PROCESSED in VIF flags to record
   the arrival of the event.

d91e8eee04 ath6kl: Configure WOW patterns while going to wow_suspend
First preference is given to the user configured WOW patterns.
If the user doesn't configure any patterns (for ex, via iw command),
the default patterns will be configured based on the current mode
(vif->nw_type) while going to WOW suspend.

Summary of changes:

  * ath6kl_wow_ap() is added to configure the below default
    patterns when the system enters into WOW suspend in AP mode.
      + Unicast IP, EAPOL-like and ARP packet pattern
      + ARP packet pattern
      + mDNS/SSDP/LLMNR pattern
      + DHCP broadcast pattern

 * ath6kl_wow_sta() is added to configure the below default
   patterns when the system enters into WOW suspend in STA mode.
      + Unicast packet pattern
      + mDNS/SSDP/LLMNR pattern

  * Move the user provided WOW patterns configuration code
    from ath6kl_wow_suspend() to a separate function called
    ath6kl_wow_usr().

  * Two argument variable's ('filter' and 'mask) data type in
    ath6kl_wmi_add_wow_pattern_cmd() are changed from 'u8 *' to
    'const u8 *'. This is needed to make all pattern and mask
    arrays to be 'static const u8' in the caller function.

  * New conditional check is added to make sure user
    configured pattern count is within the limit (WOW_MAX_FILTERS_PER_LIST).

* A new APSD power save queue is added in the station structure.
* When a station has APSD capability and goes to power save, the frame
  designated to the station will be buffered in APSD queue.
* When the host receives a frame which the firmware marked as trigger,
  host delivers the buffered frame from the APSD power save queue.
  Number of frames to deliver is decided by MAX SP length.
* When a station moves from sleep to awake state, all frames buffered
  in APSD power save queue are sent to the firmware.
* When a station is disconnected, all frames bufferes in APSD power save
  queue are dropped.
* When the host queues the first frame to the APSD queue or removes the
  last frame from the APSD queue, it is indicated to the firmware using
  WMI_AP_APSD_BUFFERED_TRAFFIC_CMD.

3ca9d1fc9a ath6kl: support for P2P mgmt operations on station interface
This patch enables support for doing P2P management operations like device
discovery on top of a station interface. After group formation, the station
interface will become a P2P GO/client interface as the case may be.

This feature requires modifications to a couple of existing WMI structures and
therefore new command ids and structures have been defined in order to be
compatible with older firmware versions and other chips. The exception here is
the wmi_connect_cmd. Adding a new field to the end of the structure will not
cause any issues with previous firmware versions since firmware only checks for
minimum length of the command. The other structures are of variable length,
hence it was not possible to add new fields to the end.

The new command ids have to be added to the end of enum wmi_cmd_id, so it has
updated to match the firmware.

The driver will support both the 'old' and the 'new' commands for a while by
checking the firmware capabilities.

Also fix a bug where we were comparing firmware scan status values
with kernel error codes, which is obviously wrong. This meant
that ath6kl didn't detect when firmware informed about failed scans. I
doubt that this fix doesn't make any difference in practise but it
still needs to be fixed. This is fixed by adding an enum for the success

a7f0c58b89 ath6kl: remove unused parameters from struct wmi
There's no use for these, at least right now, so better to remove them.
If some of them are ever needed, we can always add them back.

aa6cffc1a2 ath6kl: make sure WLAN power save is enabled during suspend
Power save is enabled during ath6kl init. But when user space disables power
save, the system will go into suspend with power save disabled. The ath6kl
driver will now explicitly enable power save prior to entering suspend and
restore its previous setting upon resume
