Hello:

This series was applied to netdev/net-next.git (main)

The driver selftest environment picks a single address family for tests
which use the generic address fields. When both IPv4 and IPv6 are
available it prefers IPv6, which can leave IPv4 paths untested and hide
IPv4-only bugs.

This happened recently in the XDP selftest, where an IPv4 checksum bug
was missed when IPv6 was also configured. XDP traffic handling has
IP-version-specific code paths, and the follow-up discussion concluded
that the XDP tests should run against both IP versions [1].

You are awesome, thank you!
