====================
nfp: flower improvement and SFF module EEPROM

The first patch in this series from Pieter improves the
handling of mangle actions in TC flower offload.  These
used to be sent down to the driver in groups, but after
Pablo N's patches they are split out causing suboptimal
expression.

The ramaining two patches from Dirk add support for reading
SFF module EEPROM data.

61f7c6f448 nfp: implement ethtool get module EEPROM
Now that the NSP provides the ability to read from the SFF modules'
EEPROM, we can use this interface to implement the ethtool callback.

If the NSP only provides partial data, we log the event from within
the driver but pass a success code to ethtool to prevent it from
discarding the partial data.

eff07b42d8 nfp: flower: reduce action list size by coalescing mangle actions
With the introduction of flow_action_for_each pedit actions are no
longer grouped together, instead pedit actions are broken out per
32 byte word. This results in an inefficient use of the action list
that is pushed to hardware where each 32 byte word becomes its own
action. Therefore we combine groups of 32 byte word before sending
the action list to hardware.

cxgb3/l2t: Fix undefined behaviour and use struct_size() helper

This patchset aims to fix an undefined behaviour when using a zero-sized

db4863fdb8 cxgb3/l2t: Use struct_size() in kvzalloc()
One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:

struct foo {
    int stuff;
    struct boo entry[];
};

size = sizeof(struct foo) + count * sizeof(struct boo);
instance = kvzalloc(size, GFP_KERNEL);

Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:

instance = kvzalloc(struct_size(instance, entry, count), GFP_KERNEL);

Notice that, in this case, variable size is not necessary, hence
it is removed.

This code was detected with the help of Coccinelle.

7649773293 cxgb3/l2t: Fix undefined behaviour
The use of zero-sized array causes undefined behaviour when it is not
the last member in a structure. As it happens to be in this case.

Also, the current code makes use of a language extension to the C90
standard, but the preferred mechanism to declare variable-length
types such as this one is a flexible array member, introduced in
C99:

struct foo {
        int stuff;
        struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last. Which is beneficial
to cultivate a high-quality code.

f5d547676c tcp: fix tcp_inet6_sk() for 32bit kernels
It turns out that struct ipv6_pinfo is not located as we think.

inet6_sk_generic() and tcp_inet6_sk() disagree on 32bit kernels by 4-bytes,
because struct tcp_sock has 8-bytes alignment,
but ipv6_pinfo size is not a multiple of 8.

sizeof(struct ipv6_pinfo): 116 (not padded to 8)

I actually first coded tcp_inet6_sk() as this patch does, but thought
that "container_of(tcp_sk(sk), struct tcp6_sock, tcp)" was cleaner.

As Julian told me : Nobody should use tcp6_sock.inet6
directly, it should be accessed via tcp_inet6_sk() or inet6_sk().

This happened when we added the first u64 field in struct tcp_sock.

The gateway setting is not per fib6_info entry but per-fib6_nh. Add a new

nh_gw is non-0 like IPv4 does.

While this increases fib6_nh by 8-bytes, the effective allocation size of
a fib6_info is unchanged. The 8 bytes is recovered later with a
fib_nh_common change.

faa041a40b ipv4: Create cleanup helper for fib_nh
Move the fib_nh cleanup code from free_fib_info_rcu into a new helper,
fib_nh_release. Move classid accounting into fib_nh_release which is
called per fib_nh to make accounting symmetrical with fib_nh_init.
Export the helper to allow for use with nexthop objects in the
future.

331c7a4023 ipv4: Move IN_DEV_IGNORE_ROUTES_WITH_LINKDOWN to helper
in_dev lookup followed by IN_DEV_IGNORE_ROUTES_WITH_LINKDOWN check
is called in several places, some with the rcu lock and others with the
rtnl held.

Move the check to a helper similar to what IPv6 has. Since the helper
can be invoked from either context use rcu_dereference_rtnl to
dereference ip_ptr.

113e59d09f Merge branch 'selftests-forwarding-Add-new-test-cases'
Ido Schimmel says:

====================
selftests: forwarding: Add new test cases

This patchset mainly adds new forwarding test cases and performs small
changes in existing infrastructure.

Patches #1-#3 add new test cases for multicast RPF check, PCP and VLAN
matching using flower and tc VLAN modify action.

The rest of the patches are from Petr who says:

In patches #4 and #5, devlink_lib.sh is fixed to first not cause double
inclusion of lib.sh, and then to deduce the device name in a simpler way.

In patch #6, helpers for dealing with shared buffer configuration are
added to devlink_lib.sh.

In patch #7, MC-awareness test is fixed to configure shared buffers
explicitly.

In patch #8, several helpers are extracted from the MC-awareness test
and put into a new mlxsw-specific library, qos_lib.sh.

In patch #9, a new test is added which checks configuration of
strictly-prioritized streams.

30905dc63b selftests: mlxsw: Add a new test for strict priority
Test that when strict priority is configured on a system, the
higher-priority traffic does actually win all the available bandwidth.
The test uses a similar approach to qos_mc_aware.sh to run and account
the traffic.

5dde21b3a7 selftests: mlxsw: qos_mc_aware: Configure shared buffers
This test runs two streams of traffic from two independent ports to
create congestion on one egress port. It is necessary to configure the
shared buffer thresholds correctly, to make sure that there is traffic
from both streams in the shared buffer. Only then can the test actually
test prioritization among these streams.

Without this configuration, it is possible, that one of the streams
takes all of port-pool quota, and the other stream is not even admitted,
thus invalidating the result.

On Spectrum-1, this is not a problem, because MC traffic uses a separate
pool. But for Spectrum-2, MC and UC share the same pool, and the correct
configuration is important.
