The network block bssid parameter can be used to force a specific BSS to
be used for a connection. It is also possible to modify this parameter
during an association. Previously, that did not result in any
notification to the driver which was somewhat problematic with drivers
that take care of BSS selection. Add a new mechanism to allow
wpa_supplicant to provide a driver update if the bssid parameter change
for the current connection modifies roaming policy (roaming
allowed/disallowed within ESS).

Even when hs20 action frame is unable to be registered,
for whatever reason, it should be possible to register
event handle for received driver messages. This patch also
avoids a segmentation fault, when p2p and hs20 were enabled
and GO NEG was unable to create p2p iface, the destroy eloop
was crashing by reading an invalid handle.

When a netdev is removed from a bridge, RTM_DELLINK message is received
with ifname (IFLA_IFNAME) pointing to the main netdev event though that
netdev is not deleted. This was causing issues with P2P GO interface
getting disabled when the netdev was removed from a bridge. Fix this by
filtering RTM_DELLINK events that are related to the bridge when
indicating interface status changes.

Some devices have limitations which do not allow changing virtual
interface mode from AP to station or vice versa. To work around this,
check if such AP interface is not dynamic. If such an interface is
enumarated, just set ifmode to AP and avoid setting nlmode to default
station mode on deinit.

When driver interface is destroyed (via wpa_driver_nl80211_deinit) the
"preq" nl socket isn't always deleted but the callback struct associated
is. After the interface is destroyed we may still get event on the
socket but as the callback has been freed this will cause wpa_supplicant
to crash.
This patch ensures that the "preq" socket is destroyed when destroying
the interface.

Commit b36935be1a ('nl80211: Fix EAPOL
frames not being delivered') and commit
147848ec4d ('nl80211: Do not add all
virtual interfaces to drv->if_indices') were not fully in sync and it
was possible for some non-hostapd use cases to end up adding undesired
ifindexes into the list of interfaces from which events and EAPOL frames
are processed on the parent interface. This could result, e.g., in P2P
Device management interface on getting unexpected events, including
RTM_NEWLINK event that could end up getting interpreted as an
indication of the interface being down and unavailable.
Make both add_ifidx() calls use the same criteria for adding interfaces
to the local list. This is not really a complete solution, but it is
good enough for now to fix the most visible side effects of this issue.

I got the below prints on a particular Android platform:
I/wpa_supplicant( 2637): nl80211: send_and_recv->nl_recvmsgs failed: 20
I/wpa_supplicant( 2637): nl80211: send_and_recv->nl_recvmsgs failed: 20
In JellyBean libnl_2 code, I see that the nl_recvmsgs returns postive values
too. In some cases, nl_recvmgs return the output of nl_recv function. nl_recv
function can return Number of bytes read, 0 or a negative error code.
Looks like this positive return value for nl_recvmsgs may be specific to
Android. While this is not how the API is supposed to work, this does no
harm with upstream libnl which returns only 0 or -1 from the function.

Commit 04eff7d5ba or something around that
timeframe may have caused a regression on how drv->if_indices gets used
with wpa_supplicant. Most (curretly likely all) wpa_supplicant virtual
interface use cases should not actually use this. This could result in
issues with P2P group interfaces delivering events to incorrect
interface (parent rather than the group interface). The previous commit
removed some of the issues, but more complete fix is to undo some of
those merged hostapd/wpa_supplicant operations.
Filter add_ifidx() uses based on hostapd vs. wpa_supplicant and iftype
to get closer to the earlier wpa_supplicant behavior for the driver
events from virtual interfaces.

It is possible for a virtual interface to be added and removed by
different parent interfaces. This can happen, e.g., with P2P group
interfaces if the P2P parent interface does not happen to be the first
entry in the wpa_supplicant global interface list. That first entry is
used to remove the group interface while the addition would have
happened with the dedicated P2P management interface.
This can result in the interface that added a new virtual interface
getting stuck with an obsolete ifindex value in the drv->if_indeces list
and as such, deliver some extra events to incorrect destination wpa_s
instance. In particular, this can result in INTERFACE_DISABLED event
from deletion of a P2P group interface getting delivered incorrectly to
the parent wpa_s instance which would disable that interface even though
the interface remains in enabled state.
Fix this by clearing the removed interface from all if_indeces lists
instead of just the one that was used to delete the interface. This is
the simplest approach since the ifindex is unique and there is no need
to track which interface added the new virtual interface to always hit
the same one when removing the interface.

bss->freq was not updated for IBSS, so whatever old value was stored
from a previous AP mode operation could end up having been used as the
channel when trying to send Authentication frames in an RSN IBSS. This
resulted in the frame not sent (cfg80211 rejects it) and potentially not
being able to re-establish connection due to 4-way handshake failing
with replay counter mismatches. Fix this by learning the operating
channel of the IBSS both when join event is received and when a
management frame is being transmitted since the IBSS may have changed
channels due to merges.

While framing the TDLS Setup Confirmation frame, the driver needs to
know if the TDLS peer is VHT/HT/WMM capable and thus shall construct the
VHT/HT operation / WMM parameter elements accordingly. Supplicant
determines if the TDLS peer is VHT/HT/WMM capable based on the presence
of the respective IEs in the received TDLS Setup Response frame.
The host driver should not need to parse the received TDLS Response
frame and thus, should be able to rely on the supplicant to indicate
the capability of the peer through additional flags while transmitting
the TDLS Setup Confirmation frame through tdls_mgmt operations.
