Jiri Pirko 007f790c82 net: introduce generic switch devices support
The goal of this is to provide a possibility to support various switch
chips. Drivers should implement relevant ndos to do so. Now there is
only one ndo defined:
- for getting physical switch id is in place.

Note that user can use random port netdevice to access the switch.

Mahesh Bandewar 2ad7bf3638 ipvlan: Initial check-in of the IPVLAN driver.
This driver is very similar to the macvlan driver except that it
uses L3 on the frame to determine the logical interface while
functioning as packet dispatcher. It inherits L2 of the master
device hence the packets on wire will have the same L2 for all
the packets originating from all virtual devices off of the same
master device.

This driver was developed keeping the namespace use-case in
mind. Hence most of the examples given here take that as the
base setup where main-device belongs to the default-ns and
virtual devices are assigned to the additional namespaces.

The device operates in two different modes and the difference
in these two modes in primarily in the TX side.

(a) L2 mode : In this mode, the device behaves as a L2 device.
TX processing upto L2 happens on the stack of the virtual device
associated with (namespace). Packets are switched after that
into the main device (default-ns) and queued for xmit.

RX processing is simple and all multicast, broadcast (if
applicable), and unicast belonging to the address(es) are
delivered to the virtual devices.

(b) L3 mode : In this mode, the device behaves like a L3 device.
TX processing upto L3 happens on the stack of the virtual device
associated with (namespace). Packets are switched to the
main-device (default-ns) for the L2 processing. Hence the routing
table of the default-ns will be used in this mode.

RX processins is somewhat similar to the L2 mode except that in
this mode only Unicast packets are delivered to the virtual device
while main-dev will handle all other packets.

The devices can be added using the "ip" command from the iproute2
package -

	ip link add link <master> <virtual> type ipvlan mode [ l2 | l3 ]

====================
pull request: wireless-next 2014-11-21

Please pull this batch of updates intended for the 3.19 stream...

For the mac80211 bits, Johannes says:

"It has been a while since my last pull request, so we accumulated
another relatively large set of changes:
 * TDLS off-channel support set from Arik/Liad, with some support
   patches I did
 * custom regulatory fixes from Arik
 * minstrel VHT fix (and a small optimisation) from Felix
 * add back radiotap vendor namespace support (myself)
 * random MAC address scanning for cfg80211/mac80211/hwsim (myself)
 * CSA improvements (Luca)
 * WoWLAN Net Detect (wake on network found) support (Luca)
 * and lots of other smaller changes from many people"

For the Bluetooth bits, Johan says:

"Here's another set of patches for 3.19. Most of it is again fixes and
cleanups to ieee802154 related code from Alexander Aring. We've also got
better handling of hardware error events along with a proper API for HCI
drivers to notify the HCI core of such situations. There's also a minor
fix for mgmt events as well as a sparse warning fix. The code for
sending HCI commands synchronously also gets a fix where we might loose
the completion event in the case of very fast HW (particularly easily
reproducible with an emulated HCI device)."

And...

"Here's another bluetooth-next pull request for 3.19. We've got:

 - Various fixes, cleanups and improvements to ieee802154/mac802154
 - Support for a Broadcom BCM20702A1 variant
 - Lots of lockdep fixes
 - Fixed handling of LE CoC errors that should trigger SMP"

For the Atheros bits, Kalle says:

"One ath6kl patch and rest for ath10k, but nothing really major which
stands out. Most notable:

o fix resume (Bartosz)

o firmware restart is now faster and more reliable (Michal)

o it's now possible to test hardware restart functionality without
  crashing the firmware using hw-restart parameter with
  simulate_fw_crash debugfs file (Michal)"

On top of that...both ath9k and mwifiex get their usual level of
updates.  Of note is the ath9k spectral scan work from Oleksij Rempel.

I also pulled from the wireless tree in order to avoid some merge issues.

Please let me know if there are problems!

Add "micrel,rmii-reference-clock-select-25-mhz" to Micrel ethernet PHY
binding documentation.

This property is needed to properly describe some revisions of Micrel
PHYs which has the function of this configuration bit inverted so that
setting it enables 25 MHz rather than 50 MHz clock mode.

Note that a clock reference ("rmii-ref") is still needed to actually

Eric Dumazet 960fb622f8 net: provide a per host RSS key generic infrastructure
RSS (Receive Side Scaling) typically uses Toeplitz hash and a 40 or 52 bytes
RSS key.

Some drivers use a constant (and well known key), some drivers use a random
key per port, making bonding setups hard to tune. Well known keys increase
attack surface, considering that number of queues is usually a power of two.

This patch provides infrastructure to help drivers doing the right thing.

netdev_rss_key_fill() should be used by drivers to initialize their RSS key,
even if they provide ethtool -X support to let user redefine the key later.

A new /proc/sys/net/core/netdev_rss_key file can be used to get the host
RSS key even for drivers not providing ethtool -x support, in case some
applications want to precisely setup flows to match some RX queues.

Tested:

myhost:~# cat /proc/sys/net/core/netdev_rss_key

Joe Perches ba7a46f16d net: Convert LIMIT_NETDEBUG to net_dbg_ratelimited
Use the more common dynamic_debug capable net_dbg_ratelimited
and remove the LIMIT_NETDEBUG macro.

All messages are still ratelimited.

Some KERN_<LEVEL> uses are changed to KERN_DEBUG.

This may have some negative impact on messages that were
emitted at KERN_INFO that are not not enabled at all unless
DEBUG is defined or dynamic_debug is enabled.  Even so,
these messages are now _not_ emitted by default.

This also eliminates the use of the net_msg_warn sysctl
"/proc/sys/net/core/warnings".  For backward compatibility,
the sysctl is not removed, but it has no function.  The extern
declaration of net_msg_warn is removed from sock.h and made
static in net/core/sysctl_net_core.c

Miscellanea:

o Update the sysctl documentation
o Remove the embedded uses of pr_fmt
o Coalesce format fragments
o Realign arguments
