The mgmt_ev_device_connected signal must be sent before any event
indications happen for sockets associated with the connection. Otherwise
e.g. device authorization for the sockets will fail with ENOTCONN as
user space things that there is no baseband link.
This patch fixes the issue by ensuring that the device_connected event
if sent (if it hasn't been so already) as soon as the first ACL data
packet arrives from the remote device.

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.

In commit b0302ab, the rtlwifi family of drivers was converted to use
asynchronous firmware loading. Unfortumately, the implementation was
racy, and the ieee80211 routines could be started before rtl_init_core()
was called to setup the data.

The date has to be updated when a patch touches the README. Therefore, nearly
every feature will modify this date. It can happens quite often that not only
one feature is currently in development or waiting on the mailinglist. This
creates merge conflicts when applying a patchset.

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.

There is a small 'error' for count values < 5, but we don't really care.

All other values from device provided buffer are byteswapped, so it seems more
logical to do same for these.

This moves the bus message definition to land together with the
other message types. This message is not used in the kernel but
I'm keeping it anyway.

This switches a horde of NDIS_*-prefixed variables to the RNDIS_*
prefix. Most of them aren't used much and causes no changes.

Switch the hyperv filter and rndis gadget driver to use the same command
enumerators as the other drivers and delete the surplus command codes.

This moves the PnP OID definitions to the RNDIS_* namespace
and puts them in the next falling slot in the list. Oh, the comment
above the PnP defines was referring to some obsolete or out-of-tree
driver so removed it, and removed my own comments telling where each
header segment came from as well, we have moved everything around by
this point anyway.

The NDIS_*-prefixed packet types have equivalent RNDIS_*-
prefixed types, besides nothing in the kernel use these defines.

Let's have a unified table of RNDIS media. We used to have a similar
table with NDIS_* prefix from the gadget driver, but since we're only
using RNDIS in the kernel (IIRC NDIS, non-remote, is for the windows-
internal network drivers so what do we care) let's prefix everything
with RNDIS. Some of the definitions were conflicting, in one of the
defines 0x0B is bearer "CO WAN" and in two others "BPC". Well I took
the majority vote. Two definition of medium 0x09 calls it "wireless
WAN" but one vote for "wireless LAN" but in this case I am sticking
with the minority, "Wide Area Network" does not make much sense in
this case as far as I can tell.
NOTE: latin singular and plural is so screwed up in these defines
that it makes my eyes bleed. But I will not attempt to submit a
patch converting all use of _MEDIA_ to _MEDIUM_ while I can probably
tell from the semantics of the code that RNDIS_MEDIA_STATE_CONNECTED
is most probably (erroneously) referring to a singular, unless it
can return an array of connected media. I suspect these erroneous
plurals are used in documentation and such so I don't want to
mess around with things for no functional change.

The 802_* network OIDs were duplicated, so let's merge them and
use the RNDIS_* prefixed definitions from the hyperV driver.
