Previously, the credential to use for a connection with a specific BSS
was picked arbitrary based on first found match of each matching
mechanism. While the credential priorities were used elsewhere, this did
not take into account that different mechanisms could find multiple
matching credentials. As such, the highest priority credential was not
always used in case more than one credential matched with the selected
BSS. Fix this by checking credential priorities again during connection
request.

For various P2P use cases, it is useful to have more accurate timestamp

Previously, only some P2P states were considered to postpone concurrent
station mode scans during group formation. Especially the WPS
provisioning step was skipped due to issues to scans run on the P2P
client interface (see commit fc6997b345).
This is not ideal since a concurrent scan can slow down group formation
considerably and potentially make it time out. Enforce p2p-in-progress
through all steps of group formation on another interface to address
this.
Signed-hostap: Jouni Malinen <jouni@qca.qualcomm.com>
Group formation timeout is normally canceled when 4-way handshake is
completed (WPA_COMPLETED -> wpas_p2p_completed). However, it is possible
for the GO to stop the group before this happens (i.e., send
Deauthentication frame with reason code 3 before 4-way handshake is
completed). This resulted in the group getting removed, but the group
formation timeout left behind. The unexpected timeout may then result in
undesired termination of the following operation. Fix this by canceling
the group formation timeout in wpas_p2p_group_delete() similarly to how
group idle timeout was canceled there.

Commit 1ff733383f added a mechanism to
work around issues due to association events and EAPOL RX events being
getting reordered. However, this applied only for the case where
wpa_supplicant is not in associated state. The same issue can happen in
roaming case with drivers that perform BSS selection internally (or in
firmware). Handle that case similarly by delaying received EAPOL frame
processing if the source address of the EAPOL frame does not match the
current BSSID.
Since wired IEEE 802.1X do not have BSSID, make this additional
workaround conditional on BSSID match having been observed during the
previous association.
This fixes issues where the initial EAPOL frame after reassociation was
either dropped (e.g., due to replay counter not increasing) or replied
to with incorrect destination address (the BSSID of the old AP). This
can result in significantly more robust roaming behavior with drivers
that do not use wpa_supplicant for BSS selection.
