Currently, the driver schedules the message to set
power save enable/disable to FW as part of the
set power mgmt command received from the userspace.
This command is then scheduled and is sent via
the scheduler thread.
Generally, userspace sets the power save disable
when it starts the DHCP process and enables the
power save back when the DHCP is completed.
DHCP packets are sent through the Datapath and the
PS enable/disable command would be sent via the
control path explained above.
the Race could happen that the scheduler was busy
with some other task and the PS disable command
was in the queue and the DHCP process began.
This would result in DHCP packets going to the peer
with PS enabled.
The fix is to set the power save enable/disable directly
instead of using the scheduler path.

Add support to fallback the PMKID generation from firmware to

In FIPS Enabled case, for roaming Firmware sends PMKID
request to host as firmware is not supposed to do crypto

selection is done in the firmware, it sends the
WMI_ROAM_PMKID_REQUEST_EVENTID. After receiving this event
the host driver triggers an event to wpa_supplicant using
NL80211_CMD_PMKSA_CANDIDATE for PMKID generation. Then
wpa_supplicant responds with PMKID to host using
NL80211_CMD_SET_PMKSA. And host updates the wmi pmk cache
and indicates the firmware via WMI_PDEV_UPDATE_PMK_CACHE_CMDID
wmi command.

Scenario:
1. Turn on SAP on channel 1 on 2.4ghz 20Mhz BW
2. Connect a STA to it.
3. Change the SAp channel to 36 80mhz BW
Observation:
STA changes the channel BW to 80 but SAP does not
send th packets in 80Mhz to the SAP.
Expectation: SAP should send the packets to STA on 80Mhz.
Issue:
SAP does not set the peer params to the FW for the peer
hence the FW keeps on sending the packets with 20Mhz
which was previously configured to it.
Fix:
Send peer params to FW for each peer so that the
packets can be sent by SAP on a max supported BW.

Fix is to avoid the AP for some time and try to
