LTP/udp6_ipsec_vti tests fail when sending large UDP datagrams over
ip6_vti that require fragmentation and the underlying device has an
MTU smaller than 1500 plus some extra space for headers. This happens
because ip6_vti, by default, sets MTU to ETH_DATA_LEN and not updating
it depending on a destination address or link parameter. Further
attempts to send UDP packets may succeed because pmtu gets updated on
ICMPV6_PKT_TOOBIG in vti6_err().
In case the lower device has larger MTU size, e.g. 9000, ip6_vti works
but not using the possible maximum size, output packets have 1500 limit.
The above cases require manual MTU setup after ip6_vti creation. However
ip_vti already updates MTU based on lower device with ip_tunnel_bind_dev().
Here is the example when the lower device MTU is set to 9000:
# ip a sh ltp_ns_veth2
ltp_ns_veth2@if7: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9000 ...
inet 10.0.0.2/24 scope global ltp_ns_veth2

# ip li show vti6
vti6@NONE: <POINTOPOINT,NOARP> mtu 1500 ...

After the patch:
# ip li add vti6 type vti6 local fd00::2 remote fd00::1
# ip li show vti6

ASoC: Fixes for v4.15
This is a fairly large set of fixes, they've been delayed partly as more
and more keep coming in. Most of them are very small driver specific
fixes, the biggest individual thing is the revert of the rcar IOMMU
support - it was causing problems and there wasn't the confidence that
it could be resolved sensibly. There's also a relatively large change
in the Freescale SSI controller which resolves some issues with the
AC'97 mode, these aren't that large in the grand scheme of things and
reflect some fairly thorough review and testing.

setplane_internal callers
lock_all_ctx in setplane_internal may return -EINTR, and
__setplane_internal could return -EDEADLK. Making more
special cases for fb would make the code even harder to
read, so the easiest solution is not taking over the fb
refcount, and making callers responsible for dropping
the ref.

When attached to the connector, the mode_valid callback will only filter
the modes provided by the connector itself as part of its probe.
However, it will not be doing it when the mode is provided by the
userspace, which still might result in a broken configuration.
In order to enforce these constraints, move our mode_valid callback to the
encoder which doesn't have this behaviour.

We handle this case correctly when needing to handle cases that violate

need to extend that padding/truncation for the 1GB alignment use case.

Before the offending commit, mlx5 core did the IRQ affinity itself,
and it seems that the new generic code have some drawbacks and one
of them is the lack for user ability to modify irq affinity after
the initial affinity values got assigned.
The issue is still being discussed and a solution in the new generic code
is required, until then we need to revert this patch.
This fixes the following issue:

nfp: flower: add Geneve tunnel support
John Hurley says:
This patchset adds support for offloading the encap and decap of Geneve
tunnels to the NFP. In both cases, specifying well known port 6081 is a
requirement for rule offload.
Geneve firmware support has been recently added, so the patchset includes
the reading of a fw symbol that defines a bitmap of newly supported
features. Geneve will only be offloaded if the fw supports it. The new
symbol is added in fw r5646.
Geneve option fields are not supported as either a match or an action due
there current exclussion from TC flower. Because Geneve (as both a match
and action) behaves the same as other udp tunnels such as VXLAN, generic
functions are created that handle both Geneve and VXLAN. It is anticapated
that these functions will be modified to support options in future
patches.
The removal of an unused variable 'tun_dst_mask' is included as a separate
patch here. This does not affect functionality.
Also included are modifications to the test framework to check that the
new encap and decap features are functioning correctly.

The tunnel dest IP is required for separate offload to the NFP. It is
already verified that a dest IP must be present and must be an exact
match in the flower rule. Therefore, we can just extract the IP from the
generated offload rule and remove the unused mask variable. The function
is then no longer required to return the IP separately.
Because tun_dst is localised to tunnel matches, move the declaration to
the tunnel if branch.

The recently added fib_metrics_match() causes a regression for routes
with both RTAX_FEATURES and RTAX_CC_ALGO if the latter has
TCP_CONG_NEEDS_ECN flag set:
| # ip link add d0 type dummy
| # ip link set d0 up
| # ip route add 172.29.29.0/24 dev d0 features ecn congctl dctcp
| # ip route del 172.29.29.0/24 dev d0 features ecn congctl dctcp
| RTNETLINK answers: No such process
During route insertion, fib_convert_metrics() detects that the given CC
algo requires ECN and hence sets DST_FEATURE_ECN_CA bit in
RTAX_FEATURES.
During route deletion though, fib_metrics_match() compares stored
RTAX_FEATURES value with that from userspace (which obviously has no
knowledge about DST_FEATURE_ECN_CA) and fails.

First, the check of &q->ring.queue against NULL is wrong, it
is always false. We should check the value rather than the address.
Secondly, we need the same check in pfifo_fast_reset() too,
as both ->reset() and ->destroy() are called in qdisc_destroy().

As noted in dwmac4_wrback_get_rx_timestamp_status the timestamp is found
in the context descriptor following the current descriptor. However the
current code looks for the context descriptor in the current
descriptor, which will always fail.

When using GMAC4 the value written in PTP_SSIR should be shifted however
the shifted value is also used in subsequent calculations which results
in a bad timestamp value.

When, during a join operation, or during message transmission, a group
member needs to be added to the group's 'congested' list, we sort it
into the list in ascending order, according to its current advertised
window size. However, we miss the case when the member is already on
that list. This will have the result that the member, after the window
size has been decremented, might be at the wrong position in that list.
This again may have the effect that we during broadcast and multicast
transmissions miss the fact that a destination is not yet ready for
reception, and we end up sending anyway. From this point on, the
behavior during the remaining session is unpredictable, e.g., with
underflowing window sizes.
We now correct this bug by unconditionally removing the member from
the list before (re-)sorting it in.
