My queue management rework broke drivers that don't
have multiple AC queues and register a single queue
only, causing a warning:
WARNING: at net/mac80211/iface.c:162 ieee80211_check_queues
This was due to filling the queues wrongly and then
noticing the error when checking later.

This represents the mass deletion of the of the tokenring support.
It gets rid of:
- the net/tr.c which the drivers depended on
- the drivers/net component
- the Kbuild infrastructure around it
- any tokenring related CONFIG_ settings in any defconfigs
- the tokenring headers in the include/linux dir
- the firmware associated with the tokenring drivers.
- any associated token ring documentation.

We are going to delete the Token ring support. This removes any
special processing in the core networking for token ring, (aside
from net/tr.c itself), leaving the drivers and remaining tokenring
support present but inert.
The mass removal of the drivers and net/tr.c will be in a separate
commit, so that the history of these files that we still care
about won't have the giant deletion tied into their history.

Commit 105bdf9ec19e729bacdb33861c74fcf3eb39eb37 introduced a
regression in L2CAP streaming mode due to rearranged initialization
code that is shared between ERTM and streaming mode. This change
makes sure the transmit queue is initialized in both modes.

e.g. device authorization for the sockets will fail with ENOTCONN as

It fixes L2CAP socket based security level elevation during a
connection. The HID profile needs this (for keyboards) and it is the only
way to achieve the security level elevation when using the management
interface to talk to the kernel (hence the management enabling patch
being the one that exposes this issue).
It enables the userspace a security level change when the socket is
already connected and create a way to notify the socket the result of the
request. At the moment of the request the socket is made non writable, if
the request fails the connections closes, otherwise the socket is made
writable again, POLL_OUT is emmited.

read_partial() always increases whatever "to" value is supplied by
adding the requested size to it, and that's the only thing it does
with that pointed-to value.
Do that pointer advance in the caller (and then only when the
updated value will be subsequently used), and change the "to"
parameter to be an in-only and non-pointer value.

In case of a client X roaming from a generic node A to another node B, it is
possible that a third node C gets A's OGM but not B's. At this point in time, if
C wants to send data to X it will send a unicast packet destined to A. The
packet header will contain A's last ttvn (C got A's OGM and so it knows it).
The packet will travel towards A without being intercepted because the ttvn
contained in its header is the newest for A.
Once A will receive the packet, A's state will not report to be in a "roaming
phase" (because, after a roaming, once A sends out its OGM, all the changes are
committed and the node is considered not to be in the roaming state anymore)
and it will match the ttvn carried by the packet. Therefore there is no reason
for A to try to alter the packet's route, thus dropping the packet because the
destination client is not there anymore.
However, C is well aware that it's routing information towards the client X is
outdated as it received an OGM from A saying that the client roamed away.
Thanks to this detail, this patch introduces a small change in behaviour: as
long as C is in the state of not knowing the new location of client X it will
forward the traffic to its last known location using ttvn-1 of the destination.
By using an older ttvn node A will be forced to re-route the packet.
Intermediate nodes are also allowed to update the packet's destination as long
as they have the information about the client's new location.
