packet (e.g., when in PS), this makes sure the packet is

For multi-vif channel switches, we want to send
NL80211_CMD_CH_SWITCH_NOTIFY to the userspace to let it decide whether
other interfaces need to be moved as well.  This is needed when we
want a P2P GO interface to follow the channel of a station, for
example.

Modify the code so that all interfaces can send CSA notifications.
Additionally, send notifications for STA CSA as well.

Add a new NL80211_CH_SWITCH_STARTED_NOTIFY message that can be sent to
the userspace when a channel switch process has started.  This allows
userspace to take action, for instance, by requesting other interfaces
to switch channel as necessary.

This patch introduces a function that allows the drivers to send this
notification.  It should be used when the driver starts processing a
channel switch initiated by a remote device (eg. when a STA receives a
CSA from the AP) and when it successfully starts a userspace-triggered
channel switch (eg. when hostapd triggers a channel swith in the AP).

Currently we ensure that the skb is freed on every error path in IPHC
decompression which makes it easy to introduce skb leaks.  By centralising
the skb_free into the receive function it makes future decompression routines
easier to maintain.  It does come at the expense of ensuring that the skb
passed into the decompression routine must not be copied.

When the RIC data element (RDE) is included in the IEs coming
from userspace for an association request, its handling is
currently broken as any IEs that are contained within it would
be split off from it and inserted again after all the IEs that
mac80211 generates (e.g. HT, VHT.)

To fix this, treat the RIC element specially, and stop after
it only when we find something that doesn't actually belong to
it. This assumes userspace is actually correctly building it,
directly after the fast BSS transition IE and before all the
others like extended capabilities.

This leaves as a potential problem the case where userspace is
building the following IEs:

[RDE] [vendor resource description] [vendor non-resource IE]

In this case, we'd erroneously consider all three IEs to be
part of the RIC data together, and not split them between the
two vendor IEs. Unfortunately, it isn't easily possible to
distinguish vendor IEs, so this isn't easy to fix. Luckily,
this case is rare as normally wpa_supplicant will include an
extended capabilities IE in the IEs, and that certainly will
break the two vendor IEs apart correctly.

This patch adds 802.11p OCB (Outside the Context of a BSS) mode
support.

When communicating in OCB mode a mandatory wildcard BSSID

The EDCA parameters handling function was changed to support

The insertion of a newly discovered STAs is done in the similar way
as in the IBSS mode -- through the deferred insertion.

The OCB mode uses a periodic 'housekeeping task' for expiration of
disconnected STAs (in the similar manner as in the MESH mode).

New Kconfig option for verbose OCB debugging outputs is added.
