Add a new QCA vendor sub command QCA_NL80211_VENDOR_SUBCMD_TX_LATENCY to
configure, retrieve, and report per-link transmit latency statistics.
When used as a command, userspace configures transmit latency monitoring
and get the corresponding statistics of the last period. When used as a
command response, driver replies the get action from userspace with the
statistics of the last period. When used as an event, driver reports the
statistics periodically.

When a CHANNEL_LIST_CHANGED event is received, memory of
iface->hw_features is freed and allocated again with
hostapd_get_hw_features(), but iface->current_mode still refer to the
original memory address, which is not correct since that memory has been
freed. This could happen in cases where the driver provides channel list
updates during the lifetime of the started BSS.
Fix this by updated iface->current_mode to point to the new array of hw
features.

wpa_supplicant could crash due to dereferencing freed memory in a corner
case. When a reestablished P2P GO group gets removed because the
hardware mode is not supported when switching from 2.4 to 5 GHz. Group
removal in wpas_p2p_group_delete() forget to clean wpa_s->last_ssid due
to the missing wpas_notify_network_removed() call before removing the
network with wpa_config_remove_network().
That could cause a crash when flushing old BSSs which age out in
wpa_bss_flush_by_age() which uses wpa_s->last_ssid in some cases.
Fix this by invoking wpas_notify_network_removed() to clean
wpa_s->last_ssid when removing a temporary P2P group network.

The MIC length depends on the negotiated group when SAE-EXT-KEY or OWE
key_mgmt is used. wlantest can determine the group if the capture file
includes the group negotiation, i.e., the initial association when a PMK
was created. However, if the capture file includes only an association
using PMKSA caching, the group information is not available. This can
result in inability to be able to process the EAPOL-Key frames (e.g.,
with the "Truncated EAPOL-Key from" message).
If the negotiated group is not known and an EAPOL-Key frame length does
not seem to match the default expectations for group 19, check whether
the alternative lengths for group 20 or 21 would result in a frame that
seems to have valid length. If so, update the STA entry with the guessed
group and continue processing the EAPOL-Key frames based on this.
