The range of addresses between 224.0.0.0 and 224.0.0.255 inclusive, is
reserved for the use of routing protocols and other low-level topology
discovery or maintenance protocols, such as gateway discovery and
group membership reporting. Multicast routers should not forward any
multicast datagram with destination addresses in this range,
regardless of its TTL.
Currently, IGMP reports are generated for this reserved range of
addresses even though a router will ignore this information since it
has no purpose. However, the presence of reserved group addresses in
an IGMP membership report uses up network bandwidth and can also
obscure addresses of interest when inspecting membership reports using
packet inspection or debug messages.
Although the RFCs for the various version of IGMP (e.g.RFC 3376 for
v3) do not specify that the reserved addresses be excluded from
membership reports, it should do no harm in doing so. In particular
there should be no adverse effect in any IGMP snooping functionality
since 224.0.0.x is specifically excluded as per RFC 4541 (IGMP and MLD
Snooping Switches Considerations) section 2.1.2. Data Forwarding
Rules:
2) Packets with a destination IP (DIP) address in the 224.0.0.X
range which are not IGMP must be forwarded on all ports.
IGMP reports for local multicast groups can now be optionally
inhibited by means of a system control variable (by setting the value
to zero) e.g.:
echo 0 > /proc/sys/net/ipv4/igmp_link_local_mcast_reports
To retain backwards compatibility the previous behaviour is retained
by default on system boot or reverted by setting the value back to
non-zero e.g.:
echo 1 > /proc/sys/net/ipv4/igmp_link_local_mcast_reports

The multicast hardware counter on 8168/8111 chips is only 32 bit while the
statistics in struct rtnl_link_stats64 are 64 bit. Given that statistics
are requested on an irregular basis, an overflow of the hardware counter
can go unnoticed. To count even very large numbers of multicast packets
reliably, add a software counter and remove previously applied code to
fill the multicast field requested by @rtl8169_get_stats64 with the values
read from the rx_multicast hardware counter.

"This is a libnvdimm ABI fixup.
I pushed back on this change quite hard given the late date, that it
appears to be purely cosmetic, sysfs is not necessarily meant to be a
user friendly UI, and the kernel interprets the reversed polarity of
the ACPI_NFIT_MEM_ARMED flag correctly. When this flag is set, the
energy source of an NVDIMM is not armed and any new writes to the DIMM
may not be preserved.
However, Bob Moore warned me that it is important to get these things
named correctly wherever they appear otherwise we run the risk of a
less than cautious firmware engineer implementing the polarity the
wrong way. Once a mistake like that escapes into production platforms
the flag becomes useless and we need to move to a new bit position.
Bob has agreed to take a change through ACPICA to rename
ACPI_NFIT_MEM_ARMED to ACPI_NFIT_MEM_NOT_ARMED, and the patch below
from Toshi brings the sysfs representation of these flags in line with
their respective polarities.
Please pull for 4.2 as this is the first kernel to expose the ACPI
NFIT sysfs representation, and this is likely a kernel that firmware
developers will be using for checking out their NVDIMM enabling"

====================
fixup IFF_NO_QUEUE conversion
This series serves two purposes:
On one hand it fixes a quite embarrassing bug around the warning I added for
drivers still setting tx_queue_len = 0 to achieve noqueue operation. It turned
out to be quite useless as due to using alloc_netdev(), many in-kernel drivers
fell into the trap by accident, as well. Instead this place serves pretty well
as a sanitizing point to set IFF_NO_QUEUE for drivers not initializing
tx_queue_len, which in turn allows to drop all special treatment of the latter
being zero since that can not happen anymore without IFF_NO_QUEUE being set.
On the other hand, it provides a better solution for Eric Dumazet's concern
regarding how to assign noqueue to an interface which does not default to it
already. In order to make this possible, noqueue is being registered so users
can 'tc qd add dev eth0 root noqueue'. In addition, it resolves the ugly
situation of 'tc qd show' not showing noqueue. Finally, the former changes
allow for some code cleanup.
====================

Now that noqueue qdisc can be attached just like any other qdisc, no
special treatment is necessary anymore when attaching it as default
qdisc.
This change has the added benefit that 'tc qdisc show' prints noqueue
instead of nothing for devices defaulting to noqueue.

Printing a warning in alloc_netdev_mqs() if tx_queue_len is zero and
IFF_NO_QUEUE not set is not appropriate since drivers may use one of the
alloc_netdev* macros instead of alloc_etherdev*, thereby not
intentionally leaving tx_queue_len uninitialized. Instead check here if
tx_queue_len is zero and set IFF_NO_QUEUE, so the value of tx_queue_len
can be ignored in net/sched_generic.c.

Commit f8d9605243 ("sctp: Enforce retransmission limit during shutdown")
fixed a problem with excessive retransmissions in the SHUTDOWN_PENDING by not
resetting the association overall_error_count. This allowed the association
to better enforce assoc.max_retrans limit.
However, the same issue still exists when the association is in SHUTDOWN_RECEIVED
state. In this state, HB-ACKs will continue to reset the overall_error_count
for the association would extend the lifetime of association unnecessarily.
This patch solves this by resetting the overall_error_count whenever the current
state is small then SCTP_STATE_SHUTDOWN_PENDING. As a small side-effect, we
end up also handling SCTP_STATE_SHUTDOWN_ACK_SENT and SCTP_STATE_SHUTDOWN_SENT
states, but they are not really impacted because we disable Heartbeats in those
states.

This enables bridge vlan_protocol to be configured through netlink.
When CONFIG_BRIDGE_VLAN_FILTERING is disabled, kernel behaves the
same way as this feature is not implemented.

Commit 62ee783bf1 ("smsc911x: Fix crash seen if neither ACPI nor OF is
configured or used") introduces an error check for the return value from
device_get_phy_mode() and bails out if there is an error. Unfortunately,
there are configurations where no phy is configured. Those configurations
now fail.
To fix the problem, accept error returns from device_get_phy_mode(),
and use the return value from device_property_read_u32() to determine
if there is a suitable firmware interface to read the configuration.

Return -ENXIO if device property array access functions don't find
a suitable firmware interface.
This lets drivers decide if they should use available platform data
instead.

For classifiers getting invoked via tc_classify(), we always need an
extra function call into tc_classify_compat(), as both are being
exported as symbols and tc_classify() itself doesn't do much except
handling of reclassifications when tp->classify() returned with
TC_ACT_RECLASSIFY.
CBQ and ATM are the only qdiscs that directly call into tc_classify_compat(),
all others use tc_classify(). When tc actions are being configured
out in the kernel, tc_classify() effectively does nothing besides
delegating.
We could spare this layer and consolidate both functions. pktgen on
single CPU constantly pushing skbs directly into the netif_receive_skb()
path with a dummy classifier on ingress qdisc attached, improves
slightly from 22.3Mpps to 23.1Mpps.

Intel Wired LAN Driver Updates 2015-08-26
This series contains updates to i40e and i40evf only.
Anjali provides a fix for i40e where the part is not receiving multicast
or VLAN tagged packets when in promiscuous mode. This can occur when a
software bridge is created on top of the device. Fixed the legacy and MSI
interrupt mode in the driver, which was non-existent before since we
were assuming MSIX was the only mode that the driver ran in. Fixed the
i40evf driver, where the wrong defines were getting used in the VF
driver.
Mitch fixes a sparse warning about comparing __le16 to u16 so use
le16_to_cpu() to resolve the warning. Also fixed a dyslexic spelling
of invalid.
Shannon adds port.crc_errors to receive CRC error counter, since it
is a receive counter.
Catherine provides a fix to move the stopping of the service task and
flow director to i40e_shutdown() instead of i40e_suspend().
Greg fixes the ethtool offline diagnostic with netqueues, which just need
to be treated the same as virtual functions when someone wants to run the
ethtool offline diagnostic test. Also fixed up code comments for the
i40e ethtool diagnostic test function. Cleans up redundant and unneeded
messages, since the kernel notifies all VXLAN capable registered drivers,
so no need to log this.
Neerav adds the ability to update statistics per VEB per traffic class
and dump it via ethtool.
Jingjing adds support for virtual channel offload to support receive
polling mode in the VF driver.
v2: dropped patch which added helper functions into a header, feedback from
David Miller was to make the functions constant to reduce the driver
footprint, so remove the patch while Anjali works on making the requested
changes.

in sctp_process_asconf(), we get address parameter from the beginning of
the addip params. but we never check if it's really there. if the addr
param is not there, it still can pass sctp_verify_asconf(), then to be
handled by sctp_process_asconf(), it will not be safe.
so add a code in sctp_verify_asconf() to check the address parameter is in
the beginning, or return false to send abort.
note that this can also detect multiple address parameters, and reject it.

While this code is #if 0'd, it'd be nicer to
