Enable configurable dfs_pri_multiplier. The ETSI typ2 type3 radar
detection ratio is lower than expected(>80%) while channel loading is
high(>30%). The host improvement for this are:
1. Add configurable dfs_pri_multiplier, controlled by
DFS_PRI_MULTIPLIER. Default value 2, min 1, max 10.
2. Lower adrastea ETSI type 2/3/4 radar filter rssi_threshold,
controlled by DFS_OVERRIDE_RF_THRESHOLD, dfs log shows that
QCS405 target report RSSI range [18, 45] while radar power
is 3 dbm. By using default rssi_threshold 24 will reject
many radar pulses, which leads to low detection ratio.
3. Calculate deltapri for each searchpri based on dfs_pri_multiplier
in dfs_count_the_other_delay_elements(), check deltapri
between [1, dfs_pri_multiplier] * refpri and searchpri, if
the primargin is desired, mark it as matched pulse.
4. Pick lowpri as refpri for the radar filter with
rf_ignore_pri_window equals to 0 while DFS_PRI_MULTIPLIER is
enabled. Observed original findref logic has some problems
which selects refpri is bigger than lowpri, which leads to
the lowpri pulses pri_match are set to 0, and in this case,
radar was not detected. Example for the issue, assume
rf->rf_pulseid 34 (ETSI type 2) has 7 pulses with pri:
1489, 2978, 2978, 2978, 1489, 2978, 1489 us in this case,
highscore is 4 (2978), scoreindex is 5, refpri is 2978, which
leads to: index 0, 4, 6 pulses with pri_match 0 in
dfs_count_the_other_delay_elements(). The fix is to select
lowpri as refpri(1489 in this case).

Hence, Add a feature flag and ini to configure the frequency

CSA on DFS channels requires CAC period after RESTART response, peers
can leave during CAC period due to HB failure. But peers remain
connected in SAP and are not deleted.
Now if vdev down is called during CAC wait period, the peer delete
all is not called, and vdev delete is sent without sending peer
delete to firmare leading to assert.
This change adds the logic to internally disconnect all peers before
channel switch if CAC is required on new channel, i.e new channel is
DFS and pre-CAC is not done and ignore cac is not set.

without configuring the FT-AKM in the network. The AP will
advertise non-FT akm with a vendor specific IE having Adaptive
11r bit set to 1 in the IE data. The AP also advertises the
MDE in beacon/probe response.
The STA should check the adaptive 11r capability if the AP
advertises MDE in beacon/probe and adaptive 11r capability in
vendor specific IE. If adaptive 11r capability is found,
STA should advertise the FT equivalent of the non-FT AKM.
Introdue a compile time flag WLAN_ADAPTIVE_11R_ENABLED to

If the AP is adaptive 11r capable, set the is_adaptive_11r_ap
