When wpa_supplicant receives a request to start a P2P group owner on a
fixed frequency with bandwidth wider than 20 MHz, wpa_supplicant scans

the primary/secondary channels if there are any other networks which are
operating on the same secondary channel. Though this logic is defined
for 20/40 MHz coexistence and might improve throughput, there are P2P
use cases where this logic causes problem:
1. The file transfer use case takes time to start the file transfer or
even fails when the 20/40 coex scan repeatedly fails due to an
ongoing externally triggered scan happening in the system.
2. wpa_supplicant overrides the channel which is selected by the

TDLS: Defer the start request until the discovery response RX for MLO
When the station (non-AP MLD) is associated with an AP MLD the link ID

ID is used in TDLS setup operation when acting as initiator. The driver
sends the received discovery response frame followed by the TDLS setup
request event. But the discovery response frame is received after the
setup request event leading to use incorrect link ID value for TDLS
setup operation causing the setup failure. Process the TDLS setup
request if the discovery response frame is received, else defer the
process until the discovery response frame is received and process the
setup request after discovery response frame is processed.
When the CHAN_SWITCH command is executed during multi BSSID case (say
BSS1, BSS2, and BSS3), if one of the BSS is disabled (say BSS2), the

next BSS (BSS3).
The CHAN_SWITCH command handler iterates over all configured BSSs and
attempts to send the switch_channel to each one. However, if any one of
the BSSs fails, the entire command is aborted and returns a failure.
Continue the iteration even if one BSS is failing to make sure the
