selftests: ethtool: Fix test when only two speeds are supported

2020-07-29T19:16:21+00:00

The test case check_highest_speed_is_chosen() configures $h1 to
advertise a subset of its supported speeds and checks that $h2 chooses
the highest speed from the subset.

To find the common advertised speeds between $h1 and $h2,
common_speeds_get() is called.

Currently, the first speed returned from common_speeds_get() is removed
claiming "h1 does not advertise this speed". The claim is wrong because
the function is called after $h1 already advertised a subset of speeds.

In case $h1 supports only two speeds, it will advertise a single speed
which will be later removed because of previously mentioned bug. This
results in the test needlessly failing. When more than two speeds are
supported this is not an issue because the first advertised speed
is the lowest one.

Fix this by not removing any speed from the list of commonly advertised
speeds.

selftests: forwarding: Add tc-police tests

2020-07-16T01:10:00+00:00

Test tc-police action in various scenarios such as Rx policing, Tx
policing, shared policer and police piped to mirred. The test passes
with both veth pairs and loopbacked ports.

# ./tc_police.sh
TEST: police on rx                                                  [ OK ]

selftests: forwarding: Add tests for ethtool extended state

2020-06-30T00:45:02+00:00

Add tests to check ethtool report about extended state.
The tests configure several states and verify that the correct extended
state is reported by ethtool.

Check extended state with substate (Autoneg) and extended state without
substate (No cable).

2020-06-30T00:45:02+00:00

Add NETIF_NO_CABLE port to tests topology.

The port can also be declared as an environment variable and tests can be
run like that:
NETIF_NO_CABLE=eth9 ./test.sh eth{1..8}

The NETIF_NO_CABLE port will be used by ethtool_extended_state test.

selftests: forwarding: Add a RED test for SW datapath

2020-06-30T00:08:28+00:00

This test is inspired by the mlxsw RED selftest. It is much simpler to set
up (also because there is no point in testing PRIO / RED encapsulation). It
tests bare RED, ECN and ECN+nodrop modes of operation. On top of that it
tests RED early_drop and mark qevents.
