[ Upstream commit 0857d6f8c759d95f89d0436f86cdfd189ef99f20 ]

Commit bdb7cc643fc9 ("ipv6: Count interface receive statistics on the
ingress netdev") does not work when ip6_forward() executes on the skbs
with vrf-enslaved netdev. Use IP6CB(skb)-&gt;iif to get to the right one.

Add a selftest script to verify.

<title>selftests: tc: Add generic mpls matching support for tc-flower</title>

<id>c09bfd9a5df933f614af909d33ada673485b46ac</id>
<content type='text'>
Add tests in tc_flower.sh for generic matching on MPLS Label Stack
Entries. The label, tc, bos and ttl fields are tested for the first
and second labels. For each field, the minimal and maximal values are
tested (the former at depth 1 and the later at depth 2).
There are also tests for matching the presence of a label stack entry
at a given depth.

In order to reduce the amount of code, all "lse" subcommands are tested
in match_mpls_lse_test(). Action "continue" is used, so that test
packets are evaluated by all filters. Then, we can verify if each
filter matched the expected number of packets.

Some versions of tc-flower produced invalid json output when dumping
MPLS filters with depth &gt; 1. Skip the test if tc isn't recent enough.

Test that setting lanes parameter is working.

Set max speed and max lanes in the list of advertised link modes,
and then try to set max speed with the lanes below max lanes if exists
in the list.

And then, test that setting number of lanes larger than max lanes fails.

Do the above for both autoneg on and off.

$ ./ethtool_lanes.sh

TEST: 4 lanes is autonegotiated                                     [ OK ]
TEST: Lanes number larger than max width is not set                 [ OK ]
TEST: Autoneg off, 4 lanes detected during force mode               [ OK ]
TEST: Lanes number larger than max width is not set                 [ OK ]

In order to test an IPv6 multicast packet we need to pass different tc

address which decides if we should generate an IPv4 or IPv6 mcast

Provide an example script which can be used as a skeleton for offloading
TCAM rules in the Ocelot switches.

Not all actions are demoed, mostly because of difficulty to automate
this from a single board.

For example, policing. We can set up an iperf3 UDP server and client and
measure throughput at destination. But at least with DSA setups, network
namespacing the individual ports is not possible because all switch
ports are handled by the same DSA master. And we cannot assume that the
target platform (an embedded board) has 2 other non-switch generator
ports, we need to work with the generator ports as switch ports (this is
the reason why mausezahn is used, and not IP traffic like ping). When
somebody has an idea how to test policing, that can be added to this
test.
