selftests: forwarding: mirror_vlan: Change test description

2018-06-04T14:08:45+00:00

The test description is displayed with the PASS/FAIL resolution after
the test is ran. There however already is one other test described
exactly like this, which makes it unclear which of the tests passed or
failed. Make the description unique.

selftests: forwarding: mirror_vlan: Uninstall trap

2018-06-04T14:08:44+00:00

Instead of installing a trap before tests run and uninstalling it after
they run, mirror_vlan.sh installs it twice due to a typo. Fix the typo.

selftests: forwarding: mirror_gre_bridge_1d_vlan: Add STP test

2018-06-01T18:11:04+00:00

To test offloading of mirror-to-gretap in mlxsw for cases that a
VLAN-unaware bridge is in underlay packet path, test that the STP status
of bridge egress port is reflected.

selftests: forwarding: mirror_gre_vlan_bridge_1q: Add more tests

2018-06-01T18:11:03+00:00

Offloading of mirror-to-gretap in mlxsw is tricky especially in cases
when the gretap underlay involves bridges. Add more tests that exercise
the bridge handling code:

- forbidden_egress tests that check vlan removal on bridge port in the
  underlay packet path
- untagged_egress tests that similarly check "egress untagged"
- fdb_roaming tests that check whether learning FDB on a different port
  is reflected
- stp tests for handling port STP status of bridge egress port

selftests: forwarding: mirror_gre_vlan_bridge_1q: Rename two tests

2018-06-01T18:11:02+00:00

Rename test_gretap_forbidden() and test_ip6gretap_forbidden() to a more
specific test_gretap_forbidden_cpu() and test_ip6gretap_forbidden_cpu().
This will make it clearer which is which when further down a patch is
introduced that forbids a VLAN on regular bridge port.

selftests: forwarding: mirror_gre_vlan_bridge_1q: Test final config

2018-06-01T18:11:02+00:00

After the final change reestablishes the original configuration, make
sure the traffic flows again as it should.

selftests: forwarding: mirror_gre_vlan_bridge_1q: Fix tunnel name

2018-06-01T18:11:02+00:00

The "ip6gretap" in the test name refers to the tunnel device type that
the test is supposed to be testing. However test_ip6gretap_forbidden()
tests, due to a typo, a gretap tunnel. Fix the typo.

selftests: forwarding: mirror_gre_lib: Add STP test

2018-06-01T18:11:02+00:00

Add a reusable full test that toggles STP state of a given bridge port
and checks that the mirroring reacts appropriately. The test will be
used by bridge tests in follow-up patches.

selftests: forwarding: mirror_lib: skip_hw the VLAN capture

2018-06-01T18:11:02+00:00

When the VLAN capture is installed on a front panel device and not a
soft device, the packets are counted twice: once in fast path, and once
after they are trapped to the kernel. Resolve the problem by passing
skip_hw flag to vlan_capture_install().

selftests: forwarding: mirror_lib: Move here do_test_span_vlan_dir_ips()

2018-06-01T18:11:01+00:00

Move the function do_test_span_vlan_dir_ips() from mirror_vlan.sh test
to a library file mirror_lib.sh to allow reuse. Fill in other entry
points similar to other testing functions in mirror_lib.sh, they will be
useful in following patches.
