This allows new vifs to be assigned to a chanctx
as long as chanctx's reservation chandefs (if any)
and chanctx's current chandef (implied by assigned
vifs at the time, if any) and the new vif chandef
are all compatible.
This implies it is impossible to assign a new vif
to an in-place reservation chanctx.
This gives no advantages for single-channel
hardware. It makes sense for multi-channel
hardware only.

At some locations, channels 149-165 are considered a single

149-161 are considered a single bundle, while channel 165 belongs
to a different bundle. This means that:
1. A station interface connection to an AP on channel 165 allows
the instantiation of a P2P GO on channels 149-165.
2. A station interface connection to an AP on channels 149-161

This allows processing of the last regulatory request when
we determine its still pending. Without this if a regulatory
request failed to get processed by userspace we wouldn't
be able to re-process it later. An example situation that can
lead to an unprocessed last_request is enabling cfg80211 to
be built-in to the kernel, not enabling CFG80211_INTERNAL_REGDB
and the CRDA binary not being available at the time the udev
rule that kicks of CRDA triggers.
In such a situation we want to let some cfg80211 triggers
eventually kick CRDA for us again. Without this if the first
cycle attempt to kick off CRDA failed we'd be stuck without
the ability to change process any further regulatory domains.
cfg80211 will trigger re-processing of the regulatory queue
whenever schedule_work(®_work) is called, currently this
happens when:
* suspend / resume
* disconnect
* a beacon hint gets triggered (non DFS 5 GHz AP found)
* a regulatory request gets added to the queue
We don't have any specific opportunistic late boot triggers
to address a late mount of where CRDA resides though, adding
that should be done separately through another patch.
Without an opportunistic fix then this fix relies at least
one of the triggeres above to happen.

With single-channel drivers, we need to be able to change a running
chanctx if we want to use chanctx reservation. Not all drivers may be
able to do this, so add a flag that indicates support for it.
Changing a running chanctx can also be used as an optimization in
multi-channel drivers when the context needs to be reserved for future
usage.
Introduce IEEE80211_CHANCTX_RESERVED chanctx mode to mark a channel as
reserved so nobody else can use it (since we know it's going to
change). In the future, we may allow several vifs to use the same
reservation as long as they plan to use the chanctx on the same

In order to support channel switch with multiple vifs and multiple
contexts, we implement a concept of channel context reservation. This
allows us to reserve a channel context to be used later.
The reservation functionality is not tied directly to channel switch
and may be used in other situations (eg. reserving a channel context
during IBSS join).
We first check if an existing compatible context exists and if it
does, we reserve it. If there is no compatible context we create a
new one and reserve it.
Additionally, split ieee80211_vif_copy_chanctx_to_vlans() so we can
call it while already holding the chanctx mutex.

It is assumed that such restrictions are enforced by user space.
Furthermore, it is assumed, that if the conditions that allowed for

the control of a local master that is acting as an AP and is
connected to AC Power.
2. Concurrent GO operation, where devices may instantiate a P2P GO
while they are under the guidance of an authorized master. For example,
on a channel on which a BSS is connected to an authorized master, i.e.,
with DFS and radar detection capability in the UNII band.

When dynamically creating interfaces from userspace, e.g. for P2P usage,
such interfaces are usually owned by the process that created them, i.e.
wpa_supplicant. Should wpa_supplicant crash, such interfaces will often
cease operating properly and cause problems on restarting the process.
To avoid this problem, introduce an ownership concept for interfaces. If
an interface is owned by a netlink socket, then it will be destroyed if
the netlink socket is closed for any reason, including if the process it
belongs to crashed. This gives us a race-free way to get rid of any such
interfaces.
