      Merge tag 'mac80211-next-for-davem-2015-01-19' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next

Some further updates for net-next:
 * fix network-manager which was broken by the previous changes
 * fix delete-station events, which were broken by me making the
   genlmsg_end() mistake
 * fix a timer left running during suspend in some race conditions
   that would cause an annoying (but harmless) warning
 * (less important, but in the tree already) remove 80+80 MHz rate
   reporting since the spec doesn't distinguish it from 160 MHz;
   as the bitrate they're both 160 MHz bandwidth

      phonet netlink: allow multiple messages per skb in route dump · 926e9878
      Johannes Berg authored 
      My previous patch to this file changed the code to be bug-compatible
towards userspace. Unless userspace (which I wasn't able to find)
implements the dump reader by hand in a wrong way, this isn't needed.
If it uses libnl or similar code putting multiple messages into a
single SKB is far more efficient.

Change the code to do this. While at it, also clean it up and don't
use so many variables - just store the address in the callback args
directly.

      The commit (3d125f9c) cause i.MX6SX sdb enet cannot work. The cause is
the commit add mdio node with un-correct phy address.

      net: sched: Introduce connmark action · 22a5dc0e
      Felix Fietkau authored 
      This tc action allows you to retrieve the connection tracking mark
This action has been used heavily by openwrt for a few years now.

There are known limitations currently:

doesn't work for initial packets, since we only query the ct table.
  Fine given use case is for returning packets

no implicit defrag.
  frags should be rare so fix later..

won't work for more complex tasks, e.g. lookup of other extensions
  since we have no means to store results

we still have a 2nd lookup later on via normal conntrack path.
This shouldn't break anything though since skb->nfct isn't altered.

V2:
remove unnecessary braces (Jiri)
change the action identifier to 14 (Jiri)
Fix some stylistic issues caught by checkpatch
V3:
Move module params to bottom (Cong)
Get rid of tcf_hashinfo_init and friends and conform to newer API (Cong)

====================
net: DSA fixes for bridge and ip-autoconf

These two patches address some real world use cases of the DSA master and slave
network devices.

You have already seen patch 1 previously and you rejected it since my
explanations were not good enough to provide a justification as to why it is
useful, hopefully this time my explanation is better.

Patch 2 solves a different, yet very real problem as well at the bridge layer
when using DSA network devices.

      net: bridge: reject DSA-enabled master netdevices as bridge members · 8db0a2ee
      Florian Fainelli authored 
      DSA-enabled master network devices with a switch tagging protocol should
strip the protocol specific format before handing the frame over to
higher layer.

When adding such a DSA master network device as a bridge member, we go
through the following code path when receiving a frame:

__netif_receive_skb_core
	-> first ptype check against ptype_all is not returning any
	   handler for this skb

	-> check and invoke rx_handler:
		-> deliver frame to the bridge layer: br_handle_frame

DSA registers a ptype handler with the fake ETH_XDSA ethertype, which is
called *after* the bridge-layer rx_handler has run. br_handle_frame()
tries to parse the frame it received from the DSA master network device,
and will not be able to match any of its conditions and jumps straight
at the end of the end of br_handle_frame() and returns
RX_HANDLER_CONSUMED there.

Since we returned RX_HANDLER_CONSUMED, __netif_receive_skb_core() stops
RX processing for this frame and returns NET_RX_SUCCESS, so we never get
a chance to call our switch tag packet processing logic and deliver
frames to the DSA slave network devices, and so we do not get any
functional bridge members at all.

Instead of cluttering the bridge receive path with DSA-specific checks,
and rely on assumptions about how __netif_receive_skb_core() is
processing frames, we simply deny adding the DSA master network device
(conduit interface) as a bridge member, leaving only the slave DSA
network devices to be bridge members, since those will work correctly in
all circumstances.

      net: ipv4: handle DSA enabled master network devices · 728c0208
      Florian Fainelli authored 
      The logic to configure a network interface for kernel IP
auto-configuration is very simplistic, and does not handle the case
where a device is stacked onto another such as with DSA. This causes the
kernel not to open and configure the master network device in a DSA
switch tree, and therefore slave network devices using this master
network devices as conduit device cannot be open.

This restriction comes from a check in net/dsa/slave.c, which is
basically checking the master netdev flags for IFF_UP and returns
-ENETDOWN if it is not the case.

Automatically bringing-up DSA master network devices allows DSA slave
network devices to be used as valid interfaces for e.g: NFS root booting
by allowing kernel IP autoconfiguration to succeed on these interfaces.

On the reverse path, make sure we do not attempt to close a DSA-enabled
device as this would implicitely prevent the slave DSA network device
from operating.

      mii: Handle link state changes for forced modes in mii_check_media() · 5bdc7380
      Ben Hutchings authored 
      mii_check_media() does not update the link (carrier) state or log link
changes when the link mode is forced.  Drivers using the mii library
must do this themselves, but most of them do not.

Instead of changing them all, provide a sensible default behaviour
similar to mii_check_link() when the mode is forced.

via-rhine depends on it being a no-op in this case, so make its call
to mii_check_media() conditional.

csiostor: Remove T4 FCoE support

We found a subtle issue with FCoE on T4 very late in the game
and decided not to productize FCoE on T4 and therefore there
are no customers that will be impacted by this change. FCoE is
supported on T5 cards.

Please apply on net-next since depends on previous commits.

Changes in v2:
  - Make the commit message more clearer.

====================
net: Add Keystone NetCP ethernet driver support

The Network Coprocessor (NetCP) is a hardware accelerator that processes
Ethernet packets. NetCP has a gigabit Ethernet (GbE) subsystem with a ethernet
switch sub-module to send and receive packets. NetCP also includes a packet
accelerator (PA) module to perform packet classification operations such as
header matching, and packet modification operations such as checksum
generation. NetCP can also optionally include a Security Accelerator(SA)
capable of performing IPSec operations on ingress/egress packets.

Keystone SoC's also have a 10 Gigabit Ethernet Subsystem (XGbE) which
includes a 3-port Ethernet switch sub-module capable of 10Gb/s and
1Gb/s rates per Ethernet port.

Both GBE and XGBE network processors supported using common driver. It
is also designed to handle future variants of NetCP.

version history
---------------
v7->v8

 - Reworked comments against v7, related to checker warning.
 - Patch 2/4 that has all of the driver code in v7 is now split into 3
   patches based on functionality so that we have 3 smaller patches
   review instead of a big patch.
 - Patch for MAINTAINER is merged to 2/4 along with netcp core driver
 - Separate patch (3/4) for 1G and  (4/4) for 10G
 - Removed big endian support for initial version (will add it later)

v6->v7
 - Fixed some minor documentation error and also modified the netcp driver
   to fix the set* functions to include correct le/be macros.

v5->v6
 - updated version after incorporating comments [6] from David Miller,
   David Laight & Geert Uytterhoeven on v5. I would like get this in
   for v3.19 merge window if the latest version is acceptable.

v4->v5
 - Sorry to spin v5 quickly but I missed few check-patch warnings which
   were pointed by Joe Perches(thanks). I folded his changes [5] along with
   few more check-patch warning fixes. I would like get this in for v3.18
   merge window if David is happy with this version.

v3->v4
 - Couple of fixes in in error path as pointed [4] out by David. Rest of
   the patches are unchanged from v3.

v2->v3
 - Update v3 after incorporating Jamal and David Miller's comment/suggestion
   from earlier versions [1] [2].  After per the discussion here [3], the
   controversial custom exports have been dropped now. And for future
   future offload support additions, we will plug into generic frameworks
   as an when they are available.

      net: netcp: Enhance GBE driver to support 10G Ethernet · 90cff9e2
      Wingman Kwok authored 
      This patch enhances the NetCP gbe driver to support 10GbE subsystem
available in Keystone NetCP. The 3-port 10GbE switch sub-module contains
the following components:- 10GbE Switch, MDIO Module, 2 PCS-R Modules
(10GBase-R) and 2 SGMII modules (10/100/1000Base-T). The GBE driver
together with netcp core driver provides support for 10G Ethernet
on Keystone SoCs.

10GbE hardware spec is available at
