selftests: forwarding: fix missing backslash

Fix missing backslash, introduced in f62c5acc800ee. Causes all tests to not be installed.

selftests: forwarding: tc_actions: allow mirred egress test to run on non-offloaded h2

2022-05-11T22:12:23Z

The host interfaces $h1 and $h2 don't have to be switchdev interfaces, but due to the fact that we pass $tcflags which may have the value of "skip_sw", we force $h2 to offload a drop rule for dst_ip, something which it may not be able to do. The selftest only wants to verify the hit count of this rule as a means of figuring out whether the packet was received, so remove the $tcflags for it and let it be done in software.

selftests: forwarding: Add a tunnel-based test for L3 HW stats

2022-05-08T10:46:21Z

Add a selftest that uses an IPIP topology and tests that L3 HW stats reflect the traffic in the tunnel. Signed-off-by: Petr Machata Signed-off-by: Ido Schimmel Signed-off-by: David S. Miller

selftests: lib: Add a generic helper for obtaining HW stats

2022-05-08T10:46:20Z

The function get_l3_stats() from the test hw_stats_l3.sh will be useful for any test that wishes to work with L3 stats. Furthermore, it is easy to generalize to other HW stats suites (for when such are added). Therefore, move the code to lib.sh, rewrite it to have the same interface as the other stats-collecting functions, and generalize to take the name of the HW stats suite to collect as an argument.

selftests: mirror_gre_bridge_1q: Avoid changing PVID while interface is operational

2022-05-03T09:21:14Z

In emulated environments, the bridge ports enslaved to br1 get a carrier before changing br1's PVID. This means that by the time the PVID is changed, br1 is already operational and configured with an IPv6 link-local address. When the test is run with netdevs registered by mlxsw, changing the PVID is vetoed, as changing the VID associated with an existing L3 interface is forbidden. This restriction is similar to the 8021q driver's restriction of changing the VID of an existing interface. Fix this by taking br1 down and bringing it back up when it is fully configured. With this fix, the test reliably passes on top of both the SW and HW data paths (emulated or not).
