Just some minor noise follow-up to address some stylistic issues of
commit 3b3ae880 ("net: sched: consolidate tc_classify{,_compat}").
Accidentally v1 instead of v2 of that commit got applied, so this

Previously, the driver would refuse to load if it couldn't secure
enough VIs from the MC to fulfill its RSS requirements.
This was causing probe to fail on later functions in
configurations where we'd run out of VIs, such as having many
VFs.

This change allows the driver to load with fewer VIs, down to a
minimum of 2. A warning will be printed saying that RSS
requirements were not met, possibly affecting performance.

efx->max_tx_channels needs to be set to avoid going down the
failure path in efx_probe_nic() immediately in the loop after the
probe() NIC-type function.
Also, Set rc=ENOSPC when bombing out of efx_probe_nic due to lack
of VIs.

Move the inetpeer_addr_base union to inetpeer_addr and drop

Both the a6 and in6_addr overlays are not needed; drop the __be32 version
and rename in6 to a6 for consistency with ipv4. Add a new u32 array to
the union which removes the need for the typecast in the compare function
and the use of a consistent arg for both ipv4 and ipv6 addresses which

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.

Pull nvdimm fixlet from Dan Williams:
 "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.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

Now that noqueue qdisc can be attached just like any other qdisc, no
special treatment is necessary anymore when attaching it as default
qdisc.

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 f8d96052 ("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.

kbuild test robot reports that certain configurations will not
automatically pick up on the "struct rt6_info" definition, so explicitly
include the header for this structure.

When CONFIG_OPENVSWITCH is set, and CONFIG_NETFILTER is not set, the
openvswitch IPv6 fragmentation handling cannot refer to ipv6_ops because
it isn't defined. Add a dummy version to avoid #ifdefs in source files.

The HW-SW contract requires mailboxes passed to the firmware to be 4KB
aligned. Previously, these mailboxes were mapped using streaming DMA
routines, which do not guarantee the bus addresses to be 4KB aligned.
Under certain conditions this constraint was indeed violated and errors
were observed.

By using consistent DMA mapping routines together with a mailbox size of
4KB we are guaranteed not to violate the constraint.

When transmit fails, it is an error, not a warning.

rocker: make master change handling nicer

Jiri Pirko (6):
  net: introduce change upper device notifier change info
  net: add netif_is_bridge_master helper
  net: add netif_is_ovs_master helper with IFF_OPENVSWITCH private flag
  net: kill long time unused bonding private flags
  rocker: use new helper to figure out master kind
  rocker: use change upper info
====================

Since now information about changed upper is passed along, benefit from
that and use this info directly.

This also fixes possible issues that could happen when non-master device
is added (current code does not distinguish between master and non-master
upper device).

Looking at rtnl kind string is kind of ugly. So use new helpers to do
this in nicer way.
