ipv4: Add sysctl knob to control early socket demux
This change is meant to add a control for disabling early socket demux.
The main motivation behind this patch is to provide an option to disable
the feature as it adds an additional cost to routing that reduces overall
throughput by up to 5%. For example one of my systems went from 12.1Mpps
to 11.6 after the early socket demux was added. It looks like the reason
for the regression is that we are now having to perform two lookups, first
the one for an established socket, and then the one for the routing table.
By adding this patch and toggling the value for ip_early_demux to 0 I am
able to get back to the 12.1Mpps I was previously seeing.

ipv4: Early TCP socket demux.
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.

net: qmi_wwan: bind to both control and data interface
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.

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.

Merge branch 'for-davem' of git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next
John Linville says:
====================
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.

bnx2x: Move the CNIC L2 CIDs to be right after the RSS CIDs
Currently the CNIC-related L2 CIDs (for sending control FCoE / iSCSI packets)
were at fixed position, according to the maximal number of RSS queues multiplied
by the number of traffic-classes. This change makes the CIDs dynamic, as they
are defined to be right after the highest RSS CID. This decreases the memory
allocated for the context.

bnx2x: Make the transmission queues adjacent
In the current scheme the transmission queues of traffic-class 0 were 0-15, the
transmission queues of traffic-class 1 were 16-31 and so on. If the number of
RSS queues was smaller than 16, there were gaps in transmission queues
numbering, as well as in CIDs numbering. This is both a waste (especially when
16 is increased to 64), and may causes problems with flushing queues when
reducing the number of RSS queues (using ethtool -L). The new scheme eliminates
the gaps.
