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

2020-07-29T19:16:21Z

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: ethtool: Move different_speeds_get() to ethtool_lib

2020-06-30T00:45:02Z

Currently different_speeds_get() is used only by ethtool.sh tests. The function can be useful for another tests that check ethtool configurations. Move the function to ethtool_lib in order to allow other tests to use it.

selftests: forwarding: Add speed and auto-negotiation test

2019-11-19T01:11:54Z

Check configurations and packets transference with different variations of autoneg and speed. Test plan: 1. Test force of same speed with autoneg off 2. Test force of different speeds with autoneg off (should fail) 3. One side is autoneg on and other side sets force of common speeds 4. One side is autoneg on and other side only advertises a subset of the common speeds (one speed of the subset) 5. One side is autoneg on and other side only advertises a subset of the common speeds. Check that highest speed is negotiated 6. Test autoneg on, but each side advertises different speeds (should fail) Signed-off-by: Amit Cohen Signed-off-by: Ido Schimmel Signed-off-by: David S. Miller
