Userspace can configure different roam control params as
defined in qca_vendor_attr_roam_control through the roam subcmd
QCA_NL80211_VENDOR_SUBCMD_ROAM and the below attributes:
QCA_ATTR_ROAM_CONTROL_SCAN_FREQ_SCHEME
QCA_ATTR_ROAM_CONTROL_CONNECTED_RSSI_THRESHOLD
QCA_ATTR_ROAM_CONTROL_CANDIDATE_RSSI_THRESHOLD
QCA_ATTR_ROAM_CONTROL_USER_REASON
Send value of above attribute to fw through command
WMI_ROAM_ENABLE_DISABLE_TRIGGER_REASON_CMDID for trigger
reason WMI_ROAM_TRIGGER_REASON_BTM_WTC.

The event WMI_ROAM_STATS_EVENTID is received after
every roam, once the roam synch complete is sent by the host.
This event contains details regarding the btm response.
This helps in debugging/understanding the scenario when roam
failure happens.
Print the info received related to btm rsp and roam initial
info into kmsg.

The band_capability field is used in other places to be
a bitmap over reg_wifi_band. Update the field in wma_tgt_cfg and
wlan_mlme_generic to take the same bitmap for consistency.
Update all references to these fields to expect a bitmap as well.

Add changes to handle transition to the 2 new states:
1. Roaming in progress: Switch to this state when roam
start notification is received from firmware.
2. Roam Synch in progress: Switch to this from RSO
STARTED state if roam synch indication event is received
from firmware. Change to this state is also allowed in
RSO STOPPED state if supplicant disabled roaming on that
vdev - to allow roam invoke to be processed.
Also query the state machine to get the roaming status instead
of using discrete flags at various layers. Clean the redundant
roaming in progress, roam synch related flags.

Rename the existing roam offload states to include
WLAN_ prefix. Add 2 new states:
WLAN_ROAMING_IN_PROG - Roaming has started at firmware, this is
after candidate selection at firmware.
WLAN_ROAM_SYNCH_IN_PROG - State after handoff is complete at
firmware.
Also move the roam_offload_state enum to connection manager.

Send Vdev pcl command on both connected STA vdev when sta+sta
roaming is enabled. Handle below cases:
1. When 1st STA is connected send PDEV pcl command for the
first sta. Set pcl_vdev_cmd_active false.
2. When 2nd STA comes up, Set pcl_vdev_cmd_active to true,
send vdev PCL for 1st sta before enabling roaming(disabled
as part of the connect on 2nd STA).
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
PCL sent for 1st STA and then send PDEV pcl command.
Also make changes to send set PCL command after roam init
is done before RSO start is done at firmware to avoid assert.
Post set pcl command from sme/csr through lim/wma/wmi to avoid
the above condition.
Disable roaming on the vdev before sending set PCL command to
avoid roaming on undesirable band & channels.

Enable compilation of the connection manager roam files with
Kbuild changes.
Add new API to store and retrieve the firmware scan channels at
mlme. Also add initial support to post SET_PCL command through
lim, so that it is not sent before ROAM init command.
Add changes to restrict connection of the 2nd STA to
channels on the other band of the 1st STA connected band.
This is done by filling only the allowed band channels in
the scan filters for the 2nd STA connection. If only
1 STA is active, it is allowed to connect on any band.
Add header gaurds for missed header files:
wlan_cm_tgt_if_tx_api.h
target_if_cm_roam_offload.h

Add new connection manager API to send vdev pcl command for
sta + sta roaming per vdev. For vdev pcl command, the weight of
the 1st sta connected band will be set to 0.
Add connection manager roam API files for TX ops,
connection manager target if wrapper to send the vdev
pcl command to wmi. Introduce new API to get dual sta
roaming support and save it in cm roam public struct.
