Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking updates from David Miller:
1) inet6_csk_update_pmtu() must return NULL or non-NULL, so translate
ERR_PTR to NULL, as needed. Fix from Eric Dumazet.
2) Fix copy&paste error in IRDA sir_dev ->set_speed method invocation,
it was testing the NULL'ness of a different method to guard the
call. Fix from Alexander Shiyan.
3) Fix build regression of xilinx driver, from Jeff Mahoney.
4) Make XEN netfront (like XEN netback) handle compound pages in SKBs
properly. From Ian Campbell.
5) Fix inverted logic of team_dev_queue_xmit() return value checks,
from Jiri Pirko and Dan Carpenter.
6) dma_poll_create() no longer allows a NULL device argument, breaking
both ixp4xx drivers. Fix from Xi Wang.
7) ne2000 driver doesn't hook up the parent device properly, breaking
udev matching. Fix from Alan Cox.
8) Locking and memory leak fixes in Near Field Communications layer.
From Thierry Escande, Szymon Janc, and Waldemar Rymarkiewicz.
9) sis900 resume regression, sis900_set_mode() is being called with the
iomem pointer instead of the expected device private. Fix from
Francois Romieu.
10) Fix IBSS regression caused by uninitializing the ibss-internals
before performing an emptyness check, from Simon WUnderlich.
11) Fix SNIFFER mode regression in iwlwifi driver, from Johannes Berg.
12) Fix task wedges in mwifiex_cmd_timeout_func(), from Bing Zhao.
13) Add back wireless sysfs directory, too much stuff depends upon it
being there (actually I'd say it never should have been removed to
begin with). From Johannes Berg.
14) Fix hang introduced by suspend/resume changes in ath9k. Fix from
Sujith Manoharan.
* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (24 commits)

of/net/mdio-gpio: Fix pdev->id issue when using devicetrees.
NFC: Fix pn533 target mode memory leak
NFC: pn533: Fix mem leak in pn533_in_dep_link_up
NFC: pn533: Fix use after free
NFC: pn533: Fix missing lock while operating on commands list
NFC: Fix nfc_llcp_local chained list insertion
ath9k_hw: Fix regression in device reset
