LL_LT_SAP supports MCC with sta interface and does not
support SCC with any interface. Add a logic to force
MCC if any STA comes up in SCC with the LL_LT_SAP interface.
This change adds below logic to force MCC on LL_LT_SAP:
1. If STA is present and LL_LT_SAP comes up, select MCC
channel in ACS and make sure to bring LL_LT_SAP on MCC channel.
2. If LL_LT_SAP starts without ACS in SCC channel, then
overwrite this SCC channel with MCC channel.
3. If LL_LT_SAP is present and STA comes up in SCC with
LL_LT_SAP, move LL_LT_SAP to an MCC channel or on different
MAC channel.
4. If LL_LT_SAP and STA are present in MCC and STA receives
CSA on LL_LT_SAP frequency resulting in SCC then move
LL_LT_SAP to MCC frequency.
5. If LL_LT_SAP and STA are present in MCC and STA roams
to LL_LT_SAP frequency resulting in SCC then move
LL_LT_SAP to MCC frequency.
Preference to lower 5 GHz will be given followed by
standalone MAC frequency then MCC frequency.

Enable CTS2SELF for specified APs that has below OUI:
Currently, STA initiates an RTS before sending a data packet and expects
AP to send CTS. The data packet would be sent out only if CTS is
received. But some APs may not respond for the RTS and station would
retry RTS frames continuously till max retry threshold is reached. It's
observed that few commercial APs have this behavior and there is no use
of sending RTS to such APs.
Identify the vendor OUI of such APs, send a self-CTS and send the
data packets. This can avoid RTS spamming also.

Offload TX data packets such as ARP response, EAPOL during roaming are
sent by firmware through HTT msg if packet capture mode is enabled.
Whenever any such packet is received via HTT msg, host inspects the
ether type of the packet and matches with the TX filter set by user
via vendor command. If the ether type matches with the TX filter set
by user, then host forwards that packet to packet capture mode interface
otherwise, drops it.
To inspect the ether type of any packet, host uses generic API which
expects packet to be in SKB format. Currently, whenever any offload
TX data packet is received in HTT msg, host wrongly passes the buffer
received in HTT msg instead of SKB to APIs expecting SKB buffer.
This leads to undefined behavior.
So, to fix above issue, whenever any offload TX data packet received,
first allocate the SKB, copy the payload buf of HTT msg which is TX
packet to SKB data and then pass that SKB to the generic APIs to get
the ether type.
Additionally, this change fixes the minor logging error.

2. PKT_CAPTURE_MGMT_CONNECT_NO_BEACON + PKT_CAPTURE_MGMT_CONNECT_BEACON +
connected_beacon_interval : to receive all other mgmt frames and only
connected SSID beacons at particular intervals
3. PKT_CAPTURE_MGMT_CONNECT_NO_BEACON +
PKT_CAPTURE_MGMT_CONNECT_SCAN_BEACON: to receive all other mgmt
frames and beacons only during scan.
But with current condition connected SSID or scan beacons config will
not be sent to FW as host checks for PKT_CAPTURE_MGMT_CONNECT_NO_BEACON
config only. Also, on reception of any beacon, host checks for only
PKT_CAPTURE_MGMT_CONNECT_NO_BEACON and if it is set, host drops the
beacon which is wrong.
So, enhance the conditions to send config to FW as well as
remove the condition on reception of any beacon so that connected SSID or
scan beacons are forwarded to packet capture interface when connected

Currently, SAP+STA and STA+SAP concurrencies are considered for
320 MHz SAP bandwidth downgrade to 160 MHz/upgrade to 320 MHz
from 160 MHz.
But during MLO link switch, a link gets disconnected and a new
link connection is started. The new link might be of 6 GHz, which
makes the sap_bw_update algo thinks that new connection/candidate
is 6 GHz and it can coexist with 320 MHz with SAP. This drives the
sap_bw_update algo to upgrade to 320 MHz, which starts policy mgr
opportunistic timer. This blocks the link switch(new link
connect operation). But this is not correct as a link is already
present and new link gets added.
Add a condition to check current bandwidth of the SAP and go for
downgrade only if the current bw is 320 MHz.
Also, cleanup the code which restarts policy mgr opportunistic
timer explicitly as timer is anyway started post
