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

policy_mgr_decr_connection_count_utfw() API is using
policy_mgr_psoc_enable() API to reset policy manager table as well
as timer deinit but it does more than resetting the table which causes
a stablity issue. For example, policy_mgr_psoc_enable() API calls to
reinitialization connection_update_done_evt event which triggers
stability issue as it has been already initialized once.
Purpose of delete all connection option is, to reset the policy
manager table, to reset any timers which can be achieved by
calling policy_mgr_psoc_disable() followed by policy_mgr_psoc_enable()

There is already existing SAP+GO combination but due to upper
layer notifying LTE-COEX event or sending command to move one of
the connections to different channel. In such cases before moving
existing connection to new channel, check if new channel can
co-exist with the other existing connection. For example, one
SAP1 is on channel-6 and second SAP2 is on channel-36 and lets
say they are doing DBS, and lets say upper layer sends LTE-COEX
to move SAP1 from channel-6 to channel-149. In this case, SAP1
and SAP2 will end up doing MCC which may not be desirable result.
When channel switch, need recheck whether concurrency is allowed,
Store the connection's parameter and temporarily delete it
from the concurrency table. This way the allow concurrency
check can be used as though a new connection is coming up,
after check, restore the connection to concurrency table.

SAP(Go) concurrency check is mainly used for two purposes:
1) When new GO/SAP session is coming up and needs to check if
this session's channel can co-exist with existing GO/SAP
sessions. For example, in case of single radio platform, MCC for
SAP/GO+SAP/GO is not supported, in such case this API should
prevent bringing the second connection.
2) There is already existing SAP+GO combination but due to upper
layer notifying LTE-COEX event or sending command to move one of
the connections to different channel. In such cases before moving
existing connection to new channel, check if new channel can
co-exist with the other existing connection. For example, one
SAP1 is on channel-6 and second SAP2 is on channel-36 and lets
say they are doing DBS, and lets say upper layer sends LTE-COEX
to move SAP1 from channel-6 to channel-149. In this case, SAP1
and SAP2 will end up doing MCC which may not be desirable result.
such cases will be prevented with this API.

channel switch rather than a new connection case.

Currently SAP-SAP concurrency on same band support is indicated through
WMI service bit wmi_service_dual_beacon_on_single_mac_scc_support and
wmi_service_dual_beacon_on_single_mac_mcc_support. If SCC is supported,
channel of desirable SAP is checked against current available SAP
interfaces. If channel is different, the desirable SAP is disallowed.
Issue is that on DBS capable platforms, this will prevent second SAP
from doing DBS.
Fix is to check if desirable channel is equal to current SAP interfaces.
If equal, SAP-SAP SCC will be allowed. Otherwise fall back to DBS checks
and SCC/MCC on single band will be rejected if above two service bits
check failed or not supported.

The driver currently changes the hw_mode based upon
the first candidate found in the scan list, and tries
to connect to it. It may happen that the connection
fails, and the STA then tries to connect to the AP
on same channel as the concurrent adapter.
It would result in hw_mode = DBS, as it is not
updated after connection success/failure.
Also if the first AP channel is in same band as that
of concurrent adapter, and the connection fails,
and the STA tries to connect to an AP in a different
band, this too is not allowed as hw_mode is not DBS
Fix is to change the hw_mode based upon the scan list.
If the driver finds any scan result which may lead to
DBS connection, the hw_mode should be set to DBS.
Once the connection is done or failed, the driver
can check and update the hw_mode again.

The driver includes the DFS channel in case of force SCC,
on 5GHz band, and rejects all 2.4Ghz band channels in the
ACS scan list in case of band_width > 40. The DFS SCC not
allowed till date prevents the SAP vdev up on that DFS channel,
hence the SAP turns on with default channel of 2.4 Ghz i.e
channel 1, because the ACS scan channel list didn't contain
any 2.4Ghz channel.
Fix is to include the 2.4Ghz channel list, and remove that DFS
channel in case the force SCC is enabled, and STA is already up
on that channel.

cause more latency(300ms) to send WMA_ROAM_OFFLOAD_SYNCH_CNF
