Scan on STA interface is taking around 10 secs to
complete. There is a 7secs expiry time used in nl
which could result in scan results received for
the first 3secs, which are from 2G channels, to

Fix is to not set offchannel simultaneous feature
capability, decrease the active dwell time for 2G
channels to 40msecs and increase burst duration
to 240msecs when GO is active.

Currently the driver calculates the nss score
based upon the max capability of the AP, and not the
hw_mde config which would be there after connection
for example, the driver calculates the score for a
2x2 11n AP, and 1x1 VHT (11ac) AP, it connects to the
11n AP in 1x1 mode, if a concurrent connection is
present, which affects throughput
Fix is to check whether the current AP channel results
in DBS or not, if yes then change the NSS to 1 instead of
2

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

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.
