In wma_get_trigger_detail_str() driver prints the roam trigger
detail for Low rssi and Periodic scan triggers, the RSSI value of
the current AP is the value before roam scan is triggered. But
the firmware considers the rssi of the current AP after roam scan
is complete to calculate the next RSSI threshold. So there could
be mismatch in the current rssi value and next rssi threshold
when roam_info->rssi_trig_data.threshold is used to print the
current AP rssi.
Use roam_info->current_rssi to print the current connected AP
rssi in the roam trigger logging.

When reassociate, roaming is disabled by wpa_supplicant, but RSO stop
reason REASON_SUPPLICANT_DISABLED_ROAMING is ignored and roam scan mode
isn't cleared to 0 before vdev WMI_ROAM_FW_OFFLOAD_ENABLE_FLAG flag is
cleared. Then host can't receive peer unmap/map event when wlan disconnect
and reconnect, host dp peer id isn't updated, Rx frames are dropped for
peer id mismatch.
Fix: When roaming is disabled, make sure roam scan mode is cleared to 0
before vdev WMI_ROAM_FW_OFFLOAD_ENABLE_FLAG flag is cleared.

Currently the driver intersects the 2g and 5g
capability and stores them in the HE cap variable
of the same PHY.
In the HW where a single PHY supports both 2g and
5g and with max BW support of 160Mhz, the intersection
of 160Mhz and 80+80Mhz MCS will lead to zero as 2g will
not support 160 and 80+80 BW. Hence the MCS map will be
0 for them indicating that the STA would support only
till MCS 7 and not above that which would lead to a
lower coding rate and lower QAM thus resulting in
a lower throughput.
Fix is to not intersect the MCS capability of 2g and 5g
and copy MCS directly from the target capability.

roaming is enabled. Handle below cases:
1. When 1st STA is connected send PDEV pcl command for the

2. When 2nd STA comes up, Set pcl_vdev_cmd_active to true,

3. For second STA force dbs connection when
enable_dual_sta_roam_offload ini is enabled. Set the channels
of the 1st connected STA band as invalid and remove these
channels from the scan filter.
4. On disconnection of 2nd STA connection, clear the vdev

Also make changes to send set PCL command after roam init
is done before RSO start is done at firmware to avoid assert.

In STA+SAP case if AP1 and STA1 have same MAC, and DUT's STA is
connected to AP1. Now when the STA1 tries to connect with DUT's SAP
peer with same mac is already present the add peer fails, but during
delete peer the DUT STA peer (AP1) is deleted instead of STA1 of
DUT's SAP. This leads to SAP deleting peer of a STA interface and
thus the SAP peer count is out of sync.

to DUT's STA. Also ad vdev check while deleting the peer in wma.

which may casue issue whenever vendor vht ie is present but vht
ie is not present in beacon. Host updates dot11 mode to

After the roaming is offloaded to Firmware when the GTK rekey
happens in Host proper KCK should be used to verify MIC.
In WPA2 GTK rekey is offloaded to Firmware but not in WPA3 case.
In WPA3 SuiteB Firmware sends KCK in Key material extended TLV
instead of Key material TLV in Roam sync indication event, as the
Keys length is more in WPA3 SuiteB. And the Key material ext TLV
is parsed improperly in driver and the same is sent in roam+auth

received in EAPOL.
This fix is to properly parse the KCK and KEK from Key buffer.
