Prefer channels that support VHT80 (and secondarily, HT40 on the same
band) over other common group channels. If no such channel is found,
prefer any channel that uses the same band so that CSA can be used. This
improves the case where a P2P GO needs to move to another channel and
there is no other reason (e.g., preferred channel from the driver or an
already used channel from a virtual interface sharing the same radio) to
pick a specific channel.

The max_oper_chwidth is parsed in wpa_config_set as INT_RANGE (see
ssid_fields). The actual parsing for INT_RANGE is done by
wpa_config_parse_int which can only store the result as full integer.
max_oper_chwidth is stored as u8 (a single byte) in wpa_ssid. This means
that on little endian systems, the least significant byte of the parsed
value are really stored in the max_oper_chwidth. But on big endian
system, the only most significant byte is stored as max_oper_chwidth.
This means that 0 is always stored because the provided range doesn't
allow any other value for systems with multi-byte-wide integers.
This also means that for common systems with 4-byte-wide integers, the
remaining 3 bytes were written after the actual member of the struct.
This should not have influenced the behavior of succeeding members
because these bytes would have been part of the padding between the
members on most systems.
Increasing its size to a full int fixes the write operations outside of
the member and allows to use the max_oper_chwidth setting on big endian
systems.

This extends the SAE implementation in both infrastructure and mesh BSS
cases to allow an optional Password Identifier to be used. This uses the
mechanism added in P802.11REVmd/D1.0. The Password Identifier is
configured in a wpa_supplicant network profile as a new string parameter
sae_password_id. In hostapd configuration, the existing sae_password
parameter has been extended to allow the password identifier (and also a
peer MAC address) to be set. In addition, multiple sae_password entries
can now be provided to hostapd to allow multiple per-peer and
per-identifier passwords to be set.

CCMP group cipher was removed if CCMP was not allowed as a pairwise
cipher when loading a configuration file (but not actually when changing
configuration during runtime). This is needed to avoid issues with
configurations that use the default group cipher (TKIP CCMP) while
modifying pairwise cipher from the default CCMP TKIP) to TKIP. However,
there is not really a need to remove the CCMP group cipher if any GCMP
or CCMP cipher is enabled as a pairwise cipher.
Change the network profile validation routine to not remove CCMP as
group cipher if CCMP-256, GCMP, or GCMP-256 is enabled as a pairwise
cipher even if CCMP is not.

Timeout is increased by dfs_cac_ms from channel data, or by max CAC time
(10 minutes) if dfs_cac_ms is not defined. This is needed for some more
complex cases, e.g., when STA is acting as an active slave with DFS
offload enabled and decided to start CAC after receiving CONNECT
command, in such a case the 10 second timeout is too small and
wpa_supplicant need to wait for CAC completion or CAC timeout (up to 10
minutes).
Without such timeout modification wpa_supplicant will be unable to
connect to an AP on DFS channel, since the default authentication
timeout (10 s) is smaller than the minimum CAC time (60 s).

When wpa_supplicant is running on a Linux interface that is configured in
promiscuous mode, and it is not a member of a bridge, incoming EAPOL
packets are processed regardless of the Destination Address in the frame.
As a consequence, there are situations where wpa_supplicant replies to
EAPOL packets that are not destined for it.
This behavior seems undesired (see IEEE Std 802.1X-2010, 11.4.a), and can
be avoided by attaching a BPF filter that lets the kernel discard packets
having pkt_type equal to PACKET_OTHERHOST.

Some wireless controllers might have separate P2P-Device interface, see
as example result of 'iw dev':
phy#0
Unnamed/non-netdev interface
...
type P2P-device
...
Interface wlp2s0
type managed

In this case there is separate 'struct wpa_supplicant' created for this
p2p-dev-* device as result of 'wpa_supplicant_add_iface >
wpas_p2p_add_p2pdev_interface > wpa_supplicant_add_iface'.
This instance of wpa_supplicant is not registered in D-Bus
(wpas_dbus_register_*) since for corresponding P2P device interface flag
'struct wpa_interface > p2p_mgmt' is set.
But this instance is saved in p2p_init_wpa_s and is used for handling
P2P related D-Bus commands. Therefore we should look for D-Bus path in
the parent of p2p_init_wpa_s instance.
