If PMKID present in AP expires, AP rejects the PMKID based association.
Current design is to clear the cache using BSSID/MAC address of link
in such cases to let a fresh SAE authentication to happen.
But host driver stores PMKSA with MLD address for ML BSS.
Adapt to the same and update PMKSA cache clear APIs to use
MLD address instead of link address.
Introduce new API which return the legacy address for non-ML
association and MLD address for MLO association of the BSS peer.
Use this API to get the correct entry from PMKSA cache to delete.
Introduce new utility API to fetch the MLD address from scan entry.

For example, If tmp_new[1] = 3, subie_len=160,
tmp_new + tmp_new[1] + MIN_IE_LEN) - sub_copy will be 159.
In this scenario, while condition gets true (159 <= 160)
In if condition (159 >= 160), we are not breaking the loop in if.
tmp_new will get incremented, tmp_new will point at 159,
tmp_new[1] will point at 160, tmp_new[2] point at 161.
So, we are accessing one byte out-of-bound value.
To fix accessing out-of-bound value subtract one from the subie_len

Currently, Scan list is trimmed based on low latency sap frequency.
But even after removal of 6 GHz frequencies from scan list,
host receives scan events for 6 GHz frequencies because rnr info

FW scans 6 GHz frequencies also.
Fix is to update hint_bssid and hint_s_ssid to those frequencies

When the STA finds a candidate AP to connect to, it checks if the
primary 20 MHz channel is punctured or not. This validation is currently
done using scan channel parameters. The scan channel parameters are
intersected to the STA's capability and might not reflect the original EHT
OP IE parameters. For example, consider an 11ax STA in HE160 MHz mode
trying to connect to a 11be AP operating in EHT320 MHz mode. The scan
channel parameters are intersected to the STA's capability of 160 MHz.
The scan channel parameters like 320 MHz center frequency and puncturing
bitmap are inconsistent with the CCFS1 and punturing bitmap received in
the EHT OP IE.
So, instead of using the intersected scan channel parameters stored in the
STA to validate puncturing bitmap of the AP, use the EHT OP IE received
from the AP to validate puncturing bitmap.

User space issues scan, which does not include non-PSC channels.
If user space does not customize these channels, kernel fills
all the supported channels (2 GHz, 5 GHz and 6 GHz all channels).
Driver does not add channels to the scan channel list even if
it is present in RNR IE, as this increases the number of channels
given by user space and increases scan time.
User space should not send customized channel list, even if it
wants to scan the RNR channels.
If the flag NL80211_SCAN_FLAG_COLOCATED_6GHZ is set or at least
one 6 GHz channel is present, driver need to add all 6 GHz
channels which are not present in the scan request and sets
RNR flag for those channels so that FW can do co-located 6 GHz
channel scans on these channels.
Without the change, Driver adds 6 GHz channels to the scan request,
which are present in PSC list only.
Withdraw logic to add all 6 GHz channels to the channel list,
if Scan req carries at least one 6 GHz channel in
scm_add_all_valid_6g_channels, which indicates that the target
or regulatory supports 6 GHz channels, as they are added if
Scan req carries NL80211_SCAN_FLAG_COLOCATED_6GHZ flag.

While processing an beacon with MBSSID IE/ IEs, the driver
creates scan entries for the TX VAP/ profile and every Non-TX
profile present in the MBSSID IE.
The scan entry generation for nontx profile happens as required,
whereas while generating the scan entry for the TX VAP, driver
copies the MBSSID IE/IEs as well. Because of this, multiple
ML IEs would be part of one frame and as a result sometimes
supplicant fails in adapting/ fetching the proper ML IE.
With this change, the host driver takes care of stripping out
the MBSSID IE/IEs from the full beacon frame and while
generating the scan entry for TX VAP/ profile, it uses the data
that only belongs to the TX VAP.
This helps in resolving the duplicate ML IE issue.
