158b090cda nl80211: Fix regression in P2P group interface removal
Commit 390e489c0d extended hostapd BSS
interface removal capabilities. However, it ended up causing a
regression in wpa_supplicant P2P group interface handling. That P2P
group interface is removed through another driver_nl80211.c BSS context
and as such, the bss->added_if is not set. Fix this by verifying whether
the request is for another ifindex and if so, removing the interface
even if added_if is not marked.

795baf773f hostapd: Filter channel list updated events after country code change
We were not filtering the EVENT_CHANNEL_LIST_CHANGED events based on the
regulatory hint initiator. So wait for EVENT_CHANNEL_LIST_CHANGED event
after our own change was triggered even when regulatory hint initiator
was the driver. This could result in the wait for the channel list to be
updated to be terminated before the real change has occurred and as
such, old channel list remaining in use when configuring
hostapd/wpa_supplicant country parameter. Fix this by filtering the
hints according to the initiator and only regulatory hints initiated by
user will be used to stop the wait.

7b7de4cf94 nl80211: Remove read-only last_freq/last_freq_ht
These variables were originally used in hostapd to clear HT channel
information when exiting. However, that functionality was lost with
commit f019981aee when moving to a common
code for setting the channel. Taken into account that no one seems to
have missed this functionality over the last four years, it seems safe
to drop this rather than try to fix the old hostapd behavior.

f0793bf191 hostapd: Wait for channel list update after country code change
If hostapd is requested to set the country code and the previous country
code differs from the new one, the channel list information from the
driver may change. This change may not be instant, so wait for an
EVENT_CHANNEL_LIST_CHANGED event before continuing interface setup with
fetching of the channel list information. This fixes issues where the
selected channel is not available based on the previous regulatory data
and update through CRDA takes some time.

f5eb9da304 nl80211: Clean up if_add() for hostapd use
The allocation of new_bss and its use was separated by a lot of code in
this function. This can be cleaned up by moving the allocation next to
the use, so that this all can be within a single #ifdef HOSTAPD block.
The i802_check_bridge() call was outside type == WPA_IF_AP_BSS case, but
in practice, it is only used for WPA_IF_AP_BSS (and if used for
something else, this would have resulted in NULL pointer dereference
anyway).
