gianfar: Fix P1010 config regression (SQ polling)
The P1010 device tree restricts the number of
supported interrupt groups to 1, although the eth
controller can support 2 interrupt groups and the
driver assumes the Multi-Group mode ("fsl,etsec2" model).
So, in this case the assumption that the Multi-Group
mode (MQ_MG_MODE) devices always support 2 interrupt
groups is false. To fix this, a check for the actual
number of interrupt groups enabled in the board's
device tree has been added in gfar_probe for the
"fsl,etsec2" devices.
Without this fix, P1010 based boards claim support for
2 Tx queues to the net stack but only one is actually
allocated, leading to NULL access in xmit. This issue
was introduced by enabling Single-Queue polling for
the P1010 devices.

csum_partial() is a complex function on x86_64, not really suited for
small number of checksummed bytes.
I spotted csum_partial() being in the top 20 most consuming functions

====================
Included changes:
- use ether_addr_copy instead of memcpy when possible
- implement new multicast packet optimisation
- improve several kerneldoc sections
- minor code cleanups
here you have our patchset for net-next/linux-3.15. They are 16
patches but most of them are just small cleanups and kerneldoc
improvements.
The only big change is the one from patch 8 to 13 by Linus Lüssing
that introduces a new multicast packets optimisation. This new
component aims to reduce the air overhead by sending multicast packets
as bat-unicast when only one destination exists or by dropping them
directly at the source if the multicast group is totally empty.
In patch 11 Linus introduces an atomic_t variable, that like others
that we already have is only object of write and read, thus making the
atomic characteristic totally useless. Unfortunately this is part of
our sysfs framework, that helps the developer to introduce new knobs
by using few macros only. For this reason we decided to keep Linus'
new knob for now, but I'd like to let you know that we are in the
process of re-working such framework in order to convert all the
current (useless) atomic_t to boolean in one go.

batman-adv: Send multicast packets to nodes with a WANT_ALL flag
With this patch a node sends IPv4 multicast packets to nodes which
have a BATADV_MCAST_WANT_ALL_IPV4 flag set and IPv6 multicast packets
to nodes which have a BATADV_MCAST_WANT_ALL_IPV6 flag set, too.
Why is this needed? There are scenarios involving bridges where
multicast report snooping and multicast TT announcements are not
sufficient, which would lead to packet loss for some nodes otherwise:
MLDv1 and IGMPv1/IGMPv2 have a suppression mechanism
for multicast listener reports. When we have an MLDv1/IGMPv1/IGMPv2
querier behind a bridge then our snooping bridge is potentially not
going to see any reports even though listeners exist because according
to RFC4541 such reports are only forwarded to multicast routers:
Note that we do not need to explicitly forward to MLDv2/IGMPv3 queriers,
because these protocols have no report suppression: A bridge has no
trouble detecting MLDv2/IGMPv3 listeners.
Even though we do not support bridges yet we need to provide the
according infrastructure already to not break compatibility later.

The extra counter and BATADV_MCAST_WANT_ALL_UNSNOOPABLES flag is needed
because with a future bridge snooping support integration a node with a
bridge on top of its soft interface is not able to reliably detect its
multicast listeners for IPv4 link-local and the IPv6

Even though this new flag does make "no difference" now, it'll ensure

====================
ptp: dynamic pin control
This patch series introduces a way of changing the auxiliary PTP
Hardware Clock functions (periodic output signals and time stamping
external signals) at run time. In the past on the netdev list, we have
discussed other ways to handle this, such as module parameters and
ethtool. This series implements a new PHC ioctl because that is the
most natural way. Users already activate the auxiliary functions via
the ioctls. The sysfs interface has also been expanded so that the pin
configuration can be programmed using shell scripts.
The first patch adds the new ioctls. The PHC subsystem does most of
the work of maintaining the function-to-pin mapping. Drivers will only
need to allocate and initialize a pin configuration table and also
provide a new method that validates a particular assignment.
Patches 5 and 6 just clean up a couple of issues in the phyter driver,
and the remaining patches actually hook the phyter's pins into the new
system.
* ChangeLog
** V3
- simplify locking in the set pin logic
** V2
- fix bug in sysfs code on init error path
- rename ptp_setpin() to ptp_set_pinfunc()
- rename .setpin() to .verify() in the driver interface

net/mlx4: Adapt code for N-Port VF
Adds support for N-Port VFs, this includes:
1. Adding support in the wrapped FW command
In wrapped commands, we need to verify and convert
the slave's port into the real physical port.
Furthermore, when sending the response back to the slave,
a reverse conversion should be made.
2. Adjusting sqpn for QP1 para-virtualization
The slave assumes that sqpn is used for QP1 communication.
If the slave is assigned to a port != (first port), we need
to adjust the sqpn that will direct its QP1 packets into the
correct endpoint.
3. Adjusting gid[5] to modify the port for raw ethernet
In B0 steering, gid[5] contains the port. It needs
to be adjusted into the physical port.
4. Adjusting number of ports in the query / ports caps in the FW commands
When a slave queries the hardware, it needs to view only
the physical ports it's assigned to.
5. Adjusting the sched_qp according to the port number
The QP port is encoded in the sched_qp, thus in modify_qp we need
to encode the correct port in sched_qp.

Intel Wired LAN Driver Updates
This series contains updates to e100, igb, igbvf, ixgbe and ixgbevf.
Stefan adds a igb patch to enable the ability strip VLAN header information
for packets bound for a VM on i350 hardware.
Joe Perches provides patches for e100, igb, igbvf, ixgbe and ixgbevf to
convert the use of __constant_<foo> to just <foo> to align with the rest
of the kernel.
Don provides two fixes for ixgbe, first resolves a link issue with DA
cables where we were not always freeing the firmware/software semaphore
after grabbing it. Second stops caching whether the management firmware
was enabled, however since this is not static, we really need to verify
with each check.
Jacob provides six fixes/cleanups for ixgbe, most notably, correct
the stop_mac_link_on d3() to check the Core Clock Disable bit before
stopping link and to fully check to see if manage firmware is running or
could be enabled before bringing down the link. Fix flow control
auto-negation for KR/KX/K4 interfaces, since setting up MAC link, the
cached autoc value and current autoc value were being incorrectly used to
determine whether link reset is required.
Emil provides a fix for ixgbe where there was a chance for aggressive
start_ndo_zmit() callers to sneak packets between enabling the Tx queues
and the link coming up. To resolve this, move the call to enable Tx
queues to after the link is established.

Jesse enables the hardware feature head write back to avoid updating the

TSO or timesync.

Dave fixes an e1000e hardware unit hang where the check for pending Tx work
when link is lost was mistakenly moved to be done only when link is first
detected to be lost. Fixed a problem with poor network performance on
certain silicon in e1000e when configured for 100M HDX performance.
Carolyn adds register defines needed for time sync functions and the code

Jacob adds the ixgbe function for writing PCI config word and checks
whether the adapter has been removed first.
Mark adds the bit __IXGBEVF_REMOVING to indicate that the module is being
removed because the __IXGBEVF_DOWN bit had been overloaded for this
purpose, but leads to trouble. ixgbevf_down function can now prevent
multiple executions by doing test_and_set_bit on __IXGBEVF_DOWN.

based on feedback from Ben Hutchings so that Mitch can re-work the
patch solution

ieee802154: properly unshare skbs in ieee802154 *_rcv functions
ieee802154 sockets do not properly unshare received skbs, which leads to
panics (at least) when they are used in conjunction with 6lowpan, so
run skb_share_check on received skbs.
6lowpan also contains a use-after-free, which is trivially fixed by
replacing the inlined skb_share_check with the explicit call.
