This resets remote parameters in both local and socket llcp structures when the
link goes down. That way, nfc_llcp_getsockopt won't return values corresponding
to the previous link parameters.

If remote_miu value is not set in the socket (i.e. connection-less socket) the

This adds support for AGF PDUs. For each PDU contained in the AGF, a new sk_buff
is allocated and dispatched to its corresponding handler.

If a new netdev (e.g. an AP VLAN) is created while the driver
has queues stopped, the new netdev queues will be started even
though they shouldn't. This will lead to frames accumulating
on the internal mac80211 pending queues instead of properly
being held on the netdev queues.

Given the (nested) switch statements, this code can't
be reached, so make it warn instead of manipulating
the carrier state which seems purposeful.

The netdev queues should always represent the state that
the driver gave them, so fiddling with them isn't really
appropriate in the mlme code. Also, since we stop queues
for flushing now, this really isn't necessary any more.
As the scan/offchannel code has also been modified to no
longer do this a while ago, remove the outdated smp_mb()
and comments about it.
While at it, also add a pair of braces that was missing.

It's unlikely that an AP requires WMM mandatory admission control
for all access categories, and if it does then we still transmit
on the background AC without requesting admission. However, avoid
using uAPSD in this case since the implementation could run into
issues and might use other ACs etc.

When a device is unplugged while suspended, mac80211 is
de-initialized and all interfaces are removed while no
state is actually present in the driver. This can cause
warnings and driver confusion.
Fix this by reordering the do_stop code to not call the
driver when it is suspended, i.e. when there's no state
in the driver anyway.
The previous patches removed a few corner cases in ROC
and virtual monitor interfaces so that now this is safe
to do and no state should be left over.

It has to be removed from the driver, but completely
destroying it helps handle unplug of a device during
suspend since then the channel context handling etc.
doesn't have to happen later when it's removed.

They can't really be executed while suspended and could
trigger work warnings, so abort all ROC items. When the
system resumes the notifications about this will be
delivered to userspace which can then act accordingly
(though it will assume they were canceled/finished.)

Most times that mesh_path_add() is called, it is followed by
a lookup to get the just-added mpath. We can instead just
return the new mpath in the case that we allocated one (or the
existing one if already there), so do that. Also, reorder the
code in mesh_path_add a bit so that we don't need to allocate
in the pre-existing case.

The mesh hwmp debug message is a bit confusing. The "sending PREP
to %p" should be the MAC address of mesh STA that has originated
the PREQ message and the "received PREP from %pM" should be the MAC
address of the mesh STA that has originated the PREP message.

Instead of open-coding the accesses and length check do

It's always just one byte, so check for that and
