selftests: drv-net: let ethtool stats settle before reading

2026-08-10T23:47:49+00:00

Some devices refresh the statistics exposed via ethtool only
periodically, every stats-block-usecs (as reported by ethtool -c).
ethtool_std_stats and ethtool_rmon sample the counters immediately
after generating traffic, so on such devices they can read stale
values and fail with a delta short of the packets just sent.

Add a hw_stats_settle() helper which sleeps for 1.25x the configured
stats-block-usecs (defaulting to 20ms when the device reports no, or
a zero, period). Use it for ethtool std stats and RMON.
The 1.25x/20msec heuristic matches what the Python tests do.

selftest: net: Extend ipmr.c for IP6MR.

2026-06-09T00:06:22+00:00

This commit extends most test cases in ipmr.c for IPV6MR.

Note that IP6MR does not provide rtnetlink interface for MFC,
so such tests are added to XFAIL_ADD().

selftests: bridge_vlan_mcast: Test toggling of multicast snooping

2026-05-20T01:15:22+00:00

Test toggling of multicast snooping when per-VLAN multicast snooping is
enabled. The test always passes, but without "bridge: mcast: Fix
possible use-after-free when removing a bridge port" it results in a
splat.

selftests: net: Add tests for failover of team-aggregated ports

2026-04-13T13:09:49+00:00

There are currently no kernel tests that verify the effect of setting
the enabled team driver option. In a followup patch, there will be
changes to this option, so it will be important to make sure it still
behaves as it does now.

The test verifies that tcp continues to work across two different team
devices in separate network namespaces, even when member links are
manually disabled.

selftests: forwarding: lib: rewrite processing of command line arguments

2026-04-09T02:26:44+00:00

The piece of code which processes the command line arguments and
populates NETIFS based on them is really unobvious. Rewrite it so that
the intention is clear and the code is easy to follow.

selftests: net: bridge_vlan_mcast: wait for h1 before querier check

2026-04-08T03:16:16+00:00

The querier-interval test adds h1 (currently a slave of the VRF created
by simple_if_init) to a temporary bridge br1 acting as an outside IGMP
querier. The kernel VRF driver (drivers/net/vrf.c) calls cycle_netdev()
on every slave add and remove, toggling the interface admin-down then up.
Phylink takes the PHY down during the admin-down half of that cycle.
Since h1 and swp1 are cable-connected, swp1 also loses its link may need
several seconds to re-negotiate.

Use setup_wait_dev $h1 0 which waits for h1 to return to UP state, so the
test can rely on the link being back up at this point.

selftests: net: update some helpers to use run_on

2026-04-02T10:11:03+00:00

Update some helpers so that they are capable to run commands on
different targets than the local one. This patch makes the necesasy
modification for those helpers / sections of code which are needed for
the ethtool_rmon.sh test that will be converted in the next patches.

For example, mac_addr_prepare() and mac_addr_restore() used when
STABLE_MAC_ADDRS=yes need to ensure stable MAC addresses on interfaces
located even in other namespaces. In order to do that, append the 'ip
link' commands with a 'run_on $dev' tag.

The same run_on is necessary also when verifying if all the interfaces
listed in NETIFS are indeed available.
