This patch cleans up the method used for determining the link speed of
devices. The old method re-wrote some logic already existing in a mac.ops
function which should be used instead. The result is much simpler to
understand and removes a strange double-check of logic, as well as reducing
code redundancy.

Input packet processing for local sockets involves two major demuxes.
One for the route and one for the socket.

But we can optimize this down to one demux for certain kinds of local
sockets.

Currently we only do this for established TCP sockets, but it could
at least in theory be expanded to other kinds of connections.

If a TCP socket is established then it's identity is fully specified.

This means that whatever input route was used during the three-way
handshake must work equally well for the rest of the connection since
the keys will not change.

Once we move to established state, we cache the receive packet's input
route to use later.

Like the existing cached route in sk->sk_dst_cache used for output
packets, we have to check for route invalidations using dst->obsolete
and dst->ops->check().

Early demux occurs outside of a socket locked section, so when a route
invalidation occurs we defer the fixup of sk->sk_rx_dst until we are
actually inside of established state packet processing and thus have
the socket locked.

Always bind to control interface regardless of whether
it is a shared interface or not.

A QMI/wwan function is required to provide both a control
interface (QMI) and a data interface (wwan).  All devices
supported by this driver do so.  But the vendors may
choose to use different USB descriptor layouts, and some
vendors even allow the same device to present different
layouts.

Most of these devices use a USB descriptor layout with a
single USB interface for both control and data.  But some
split control and data into two interfaces, bound together
by a CDC Union descriptor on the control interface. Before
the cdc-wdm subdriver support was added, this split was
used to let cdc-wdm drive the QMI control interface and
qmi_wwan drive the wwna data interface.

This split driver model has a number of issues:
 - qmi_wwan must match on the data interface descriptor,
   which often are indistiguishable from data interfaces
   belonging to other CDC (like) functions like ACM
 - supporting a single QMI/wwan function requires adding
   the device to two drivers
 - syncronizing the probes among a number of drivers, to
   ensure selecting the correct driver, is difficult unless
   all drivers match on the same interface

This patch resolves these problems by using the same
probing mechanism as cdc-ether for devices with a two-
interface USB descriptor layout.  This makes the driver
behave consistently, supporting both the control and data
part of the QMI/wwan function, regardless of the USB
descriptors.

====================
here is our second pull request for net-next. In this series Federico
Vaga adds a pci driver for c_can/d_can hardware using the existing
generic c_can driver. The remaining 6 patches are by Oliver Hartkopp.
He adds CANFD support to the CAN stack while keeping binary
compatibility for existing applications. CANFD is an extension to the
existing CAN standard, it allows longer CAN frames and/or higher data
rates. There's no real hardware available yet, but this series adds
CANFD support to the vcan driver.

====================
This is a sizeable batch of updates intended for 3.6...

The bulk of the changes here are Bluetooth.  Gustavo says:

	Here goes the first Bluetooth pull request for 3.6, we have
	queued quite a lot of work. Andrei Emeltchenko added the AMP
	Manager code, a lot of work is needed, but the first bit are
	already there. This code is disabled by default.  Mat Martineau
	changed the whole L2CAP ERTM state machine code, replacing
	the old one with a new implementation. Besides that we had
	lot of coding style fixes (to follow net rules), more l2cap
	core separation from socket and many clean ups and fixed all
	over the tree.

Along with the above, there is a healthy dose of ath9k, iwlwifi,
and other driver updates.  There is also another pull from the
wireless tree to resolve some merge issues.  I also fixed-up some
merge discrepencies between net-next and wireless-next.
