When the wiphy supports multiple bands and reports different capability
values between 5 GHz and 6 GHz channels, the 6 GHz mesh interface is
unable to correctly map the channel width in function
ibss_mesh_setup_freq(). This issue arises because the modes of 5 GHz and
6 GHz interfaces are the same (HOSTAPD_MODE_IEEE80211A) in supported
modes.
To address this, use function get_mode() to determine the appropriate
mode during mesh setup. This will iterates through all the hw_features
sets and ensures compatibility with the band of the channel supported in
hw_features set.

wpa_supplicant might use a wrong BSS entry with the SSID different from
the current SSID of the current BSS while processing a roam event from
the driver when wpa_supplicant has a stale BSS entry with the old SSID
and the driver roams to the same BSS after it is restarted with a new
SSID.
To avoid this, update scan results from the driver when a BSS entry is
not found with the current SSID and try to fetch the BSS entry again
with the current SSID after this.
Also, with this change wpa_supplicant_get_new_bss() itself will update
the BSS table and search for the current BSS entry if it is not found in
the BSS table. So, remove the BSS table update and search logic from the
callers of wpa_supplicant_get_new_bss().

Allocate static IPv4 address in EAPOL frames during 4-way handshake
instead of DHCP when using P2P invitation. wpa_s->current_bss needs to
be set for the P2P specific IP address assignment mechanism to be used
in wpa_supplicant_rsn_supp_set_config(). This worked for the initial P2P
connection, but not for some cases reinvoking a persistent group.
Since there is only one AP (P2P GO) in the P2P client case, the
conditions added in commit 4d3be9cdd1 ("Postpone updating of
wpa_s->current_bss till association event") are not needed and the
easiest approach for this is to allow current_bss to be set for
p2p_in_invitation cases. If the GO P2P Interface Address (BSSID) could
be determined for all the related cases, this could be addressed a bit
more cleanly by setting the go_bssid argument for
wpas_start_p2p_client(), but that can be left as a possible future step.

Commit 117e812d06 ("Update BSS table entry if roaming event indicates
frequency change") added wpa_supplicant BSS table update based on the
latest driver scan results whenever processing an association event that
results in the current operating channel changing. While that is needed
to cover the case where an AP changes its own operating channel (and
that is noticed as a roam or new connection instead of a channel switch
event), this should not really be needed for cases where the
wpa_supplicant entry for the new BSS is already up to date.
Skip the full BSS table update on association event if the event is for
a roaming case to a different BSS and the BSS entry for the target is
already available and for the current operating channel. This avoids
undesired latency when processing the association event.
