The following patchset contain updates for your net-next tree, they are:

* Fix (for just added) connlabel dependencies, from Florian Westphal.

* Add aliasing support for conntrack, thus users can either use -m state
  or -m conntrack from iptables while using the same kernel module, from
  Jozsef Kadlecsik.

* Some code refactoring for the CT target to merge common code in
  revision 0 and 1, from myself.

* Add aliasing support for CT, based on patch from Jozsef Kadlecsik.

* Add one mutex per nfnetlink subsystem, from myself.

* Improved logging for packets that are dropped by helpers, from myself.

Pull in 'net' to take in the bug fixes that didn't make it into
3.8-final.

Also, deal with the semantic conflict of the change made to
net/ipv6/xfrm6_policy.c   A missing rt6->n neighbour release
was added to 'net', but in 'net-next' we no longer cache the
neighbour entries in the ipv6 routes so that change is not
appropriate there.

Connection tracking helpers have to drop packets under exceptional
situations. Currently, the user gets the following logging message
in case that happens:

	nf_ct_%s: dropping packet ...

However, depending on the helper, there are different reasons why a
packet can be dropped.

This patch modifies the existing code to provide more specific
error message in the scope of each helper to help users to debug
the reason why the packet has been dropped, ie:

	nf_ct_%s: dropping packet: reason ...

Thanks to Joe Perches for many formatting suggestions.

John W. Linville says:

====================
This probably is the last big pull request for wireless bits
for 3.9.  Of course, I'm sure there will be a few stragglers here
and there...surely a few bug fixes as well... :-) (In fact, I see
that Johannes has already queued-up a few more for me while I was
preparing this...)

Included are a number of pulls...

For mac80211-next, Johannes says:

"The biggest change I have is undoubtedly Marco's mesh powersave
implementation. Beyond that, I have a patch from Emmanuel to modify the
DTIM period API in mac80211, scan improvements and a removal of some
previous workaround code from Stanislaw, dynamic short slot time from
Thomas and 64-bit station byte counters from Vladimir. I also made a
number of changes myself, some related to WoWLAN, some auth/deauth
improvements and most of them BSS list cleanups."

"This time, I have relatively large number of fixes in various areas of
the code (a memory leak in regulatory, an RX race in mac80211, the new
radar checking caused a P2P device problem, some mesh issues with
stations, an older bug in tracing and for kernel-doc) as well as a
number of small new features. The biggest (in the diffstat) is my work
on hidden SSID tracking."

"Please pull to get
 * radar detection work from Simon
 * mesh improvements from Thomas
 * a connection monitoring/powersave fix from Wojciech
 * TDLS-related station management work from Jouni
 * VLAN crypto fixes from Michael Braun
 * CCK support in minstrel_ht from Felix
 * an SMPS (not SMSP, oops) related improvement in mac80211 (Emmanuel)
 * some WoWLAN work from Amitkumar Karwar: pattern match offset and a
   documentation fix
 * some WoWLAN work from myself (TCP connection wakeup feature API)
 * and a lot of VHT (and some HT) work (also from myself)

And a number of more random cleanups/fixes. I merged mac80211/master to
avoid a merge problem there."

And regarding iwlwifi-next, Johannes says:

"We continue work on our new driver, but I also have a WoWLAN and AP mode
improvement for the previous driver and a change to use threaded
interrupts to prepare us for working with non-PCIe devices."

Regarding wl12xx, Luca says:

"A few more patches intended for 3.9.  Mostly some clean-ups I've been
doing to make it easier to support device-tree.  Also including one bug
fix for wl12xx where the rates we advertise were wrong and an update in
the wlconf structure to support newer firmwares."

For the nfc-next bits, Samuel says:

"This is the second NFC pull request for 3.9.

We have:

- A few pn533 fixes on top of Waldemar refactorization of the driver, one of
  them fixes target mode.

- A new driver for Inside Secure microread chipset. It supports two
  physical layers: i2c and MEI. The MEI one depends on a patchset that's
  been sent to Greg Kroah-Hartman for inclusion into the 3.9 kernel [1]. The
  dependency is a KConfig one which means this code is not buildable as long
  as the MEI API is not usptream."

"This 3rd NFC pull request for 3.9 contains a fix for the microread MEI
physical layer support, as the MEI bus API changed.

From the MEI code, we now pass the MEI id back to the driver probe routine,
and we also pass a name and a MEI id table through the mei_bus_driver
structure. A few renames as well like e.g. mei_bus_driver to mei_driver or
mei_bus_client to mei_device in order to be closer to the driver model
practices."

For the ath6kl bits, Kalle says:

"There's not anything special here, most of the patches are just code
cleanup. The only functional changes are using the beacon interval from user
space and fixing a crash which happens when inserting and removing the
module in a loop."

Also, I pulled the wireless tree in order to resolve some pending
merge issues.  On top of that, there is a bunch of work on brcmfmac
that leads up to P2P support.  Also, mwifiex, rtlwifi, and a variety
of other drivers see some basic cleanups and minor enhancements.

Please let me know if there are problems!

Upper case macros for various chip attributes are slightly

tg3_<foo> attribute functions.

Convert:

GET_ASIC_REV(tp->pci_chip_rev_id)       -> tg3_asic_rev(tp)
GET_CHIP_REV(tp->pci_chip_rev_id)       -> tg3_chip_rev(tp)

GET_METAL_REV(tp->pci_chip_rev_id)      -> tg3_metal_rev(tp) (unused)

Add:
tg3_chip_rev_id(tp) for tp->pci_chip_rev_id so access styles
are similar to tg3_asic_rev and tg3_chip_rev.

These macros are not converted to static inline functions
because gcc (tested with 4.7.2) is currently unable to

is otherwise larger.

Jeff Kirsher says:

====================
This series contains updates to e1000, e1000e, igb, igbvf and ixgbe.
The e1000, e1000e, igb and igbvf are single patch changes and the
remaining 11 patches are all against ixgbe.

The e1000 patch is a comment cleanup to align e1000 with the code
commenting style for /drivers/net.  It also contains a few other white
space cleanups (i.e. fix lines over 80 char, remove unnecessary blank
lines and fix the use of tabs/spaces).

The e1000e patch from Koki (Fujitsu) adds a warning when link speed is
downgraded due to SmartSpeed.

The igb patch from Stefan (Red Hat) increases the timeout in the ethtool
offline self-test because some i350 adapters would sometimes fail the
self-test because link auto negotiation may take longer than the current
4 second timeout.

The igbvf patch from Alex is meant to address several race issues that
become possible because next_to_watch could possibly be set to a value
that shows that the descriptor is done when it is not.  In order to correct
that we instead make next_to_watch a pointer that is set to NULL during
cleanup, and set to the eop_desc after the descriptor rings have been written.

The remaining patches for ixgbe are a mix of fixes and added support as well
as some cleanup.  Most notably is the added support for displaying the
number of Tx/Rx channels via ethtool by Alex.  Also Aurélien adds the
ability for reading data from SFP+ modules over i2c for diagnostic
monitoring.

Recent changes have made it so that MAX_SKB_FRAGS is now never less than 16.
As a result we were seeing issues on systems with 64K pages as it would
cause DESC_NEEDED to increase to 68, and we would need over 136 descriptors
free before clean_tx_irq would wake the queue.

This patch makes it so that DESC_NEEDED is always MAX_SKB_FRAGS + 4.  This
should prevent any possible deadlocks on the systems with 64K pages as we will
now only require 42 descriptors to wake.

Instead of adjusting the FCoE and Flow director limits based on the number
of CPUs we can define them much sooner.  This allows the user to come
through later and adjust them once we have updated the code to support the
set_channels ethtool operation.

I am still allowing for FCoE and RSS queues to be separated if the number
queues is less than the number of CPUs.  This essentially treats the two
groupings like they are two separate traffic classes.

In addition I am changing the initialization to use the MAX_TX/RX_QUEUES
defines instead of trying to compute the value as it will be possible in
upcoming patches for the user to request the maximum number of queues.

I have also updated things so that the upper limit on queues is exactly 63
instead of allowing it to go up to 64.  The reason for this change is to
address the fact thqt the driver only supports up to 63 queue vectors since
the hardware supports 64 MSI-X vectors, but one must be reserved for "other"
causes.
