8a32229408 qcacmn: Add rate limiting to scm prints
Heavy print from scan module slowing down
frame processing and caused the scheduler
buffer to be full causing buffer full assert

Move scm_err to scm_err_rl which will add
print rate limiting

ab48ce3502 qcacmn: Fix connection issue with hidden ssid in DFS channel
Repeater AP failed to associate to Root AP with
hidden ssid in DFS channel.

Normally probe request is sent in passive channels if beacon
from AP is found. With strict passive scan, probe request is
not sent in passive channels even after beacon is found in that
channel.

If AP is configured in hidden ssid, Client/STA does not get the
Probe Response and thus, no SSID information is present in the
scan table to start authentication.

To overcome this, user needs to set the desired {BSSID, SSID} pair,
Example: Desired pair = {00:03:7F:AA:BB:CC, MOON1},
so that when driver receives a beacon it compares the
BSSID and updates the SSID field to update the scan table.

In general, we already set the ssid in sta configuration
But in this case, we also need to configure BSSID of the hidden AP.
This can be configured through iwpriv cmd.
Example: iwpriv athx conf_bssid 11:03:7F:46:03:17

cb5ce20e28 qcacmn: Remove DBS logic from scm_calculate_nss_score
Driver calculates nss score for BSS, depending upon the
current DBS status. Thus it does not give more preference
to 2x2 and considers it the same as 1x1.
But the DBS condition can change and driver
can move to single mac.

Fix to give more preference to 2x2 BSS so that
better throughput can be achieved in single mac.

bfbf4422a7 qcacmn: Fix qbss calculation in case of good RSSI threshold
Currently, when Current RSSI is better than good RSSI threshold
first driver calculates qbss percentage and set qbss score accordingly
and when current RSSI is weaker than or equal to good RSSI threshold
(-70dBm) driver directly sets 10% as qbss score. But as per requirement
Driver should calulate qbss percentage in order to set qbss score for
RSSI = -70db

Fix is to allow driver to ignore qbss percentag calculation only
when current RSSI is less than good RSSI threshold.

3bdf380c03 qcacmn: Don't process scan command when vdev delete is in process
When driver performs vdev delete operation, it changes vdev state
to logically deleted or physically deleted only after receiving vdev
delete command's response from FW. In between (sending vdev del req
and receiving vdev del rsp) if thread gets pre-empted and other thread
start posting command (like scan command) to process then it could
lead to use after free scenario.

Notify scan component when vdev delete is intiated and let scan
component record that in to vdev's scan private object as one of the
flags.

check this flag before processing the scan command.

49f9618acc qcacmn: Allow broadcast probe req for p2p scan with empty SSID
In case where driver receives a scan request with a single SSID with
an empty string, it must be treated as an active scan with broadcast
probe requests. In case of p2p search, driver treats this as a passive
scan. With this the P2P Client fails to detect existing P2P GO or
Autonomous GO devices, leading to connection failure.

Set flag WMI_SCAN_ADD_BCAST_PROBE_REQ for this type of p2p scan req.
P2P GO devices will respond to probe requests with wildcard SSID
and Cli will be able to connect to them.

is derived from psoc_handle at the WMI layer instead of using
the wmi_handle passed from the above layer i.e target_if

c176a5241b qcacmn: Use cookie instead of bool to check if scan node is active
Currently bool is used to check if scan node is active or not, and
if it is active the deletion can happen. Now if two thread tries to
delete the same node at same time, the first one to get the node
will delete the node and set the active bool to false. If the
delete operation leads to node being freed, the 2nd thread when gets
the lock tries to check the bool, if node is active and then return
if node is not active.

Now if before the 2nd thread check the bool, the memory is reallocate
and the byte pointing to the bool is overwritten with non-zero value
the 2nd thread will assume that node is still active and try to delete
and access an already freed node.

To fix this use cookie instead of bool to check if scan node is active.
