It looks like cfg80211 can deliver a deauth/disassoc event during some

Avoid issues with such disconnection event resulting in core

Commit c3fea27274 added a call to clear
all other PMKSA cache entries for the same network if the PMKSA cache
entry of the current AP changed. This was needed to fix OKC cases since
the other APs would likely use the new PMK in the future. However, this
ended up clearing entries in cases where that is not desired and this
resulted in needing additional full EAP authentication with networks
that did not support OKC if wpa_supplicant was configured to try to use
it.
Make PMKSA cache entry flushing more limited so that the other entries
are removed only if they used the old PMK that was replaced for the
current AP and only if that PMK had previously been used successfully
(i.e., opportunistic flag was already cleared back to 0 in
wpa_supplicant_key_neg_complete()). This is still enough to fix the
issue described in that older commit while not causing problems for
standard PMKSA caching operations even if OKC is enabled in

TDLS responder STA used to retransmit the TDLS Setup Response after 5
seconds if the TDLS Setup Confirm is not received. The initiator would
have enabled the TDLS link and started transmitting the data to the peer
on the TDLS link after transmitting the TDLS Setup Confirm frame. If the
TDLS Setup Confirm frame is not received by the receiver, the
transmissions from the initiator on the direct link would get failed for
the TDLS link not getting enabled on the receiver. This commit reduces
the data delivery failure duration by shortening the retry time of the
TDLS Setup Response frames. The retry limit of the TDLS Response frame
also is increased to ensure that the peer does not miss the frames in
