this apparently causes rtnetlink.sh self-tests failures:

https://netdev.bots.linux.dev/flakes.html?tn-needle=rtnetlink-sh

example failure:

https://netdev-3.bots.linux.dev/vmksft-net/results/467721/18-rtnetlink-sh/stdout

the ipsec_offload test (using netdevsim) fails.

@Jakub: it looks like the rtnetlink.sh test is currently ignored by
patchwork, skimming over the recent failures they are roughly
correlated to this series submission: the test looks otherwise
reasonably stable to me.

Cheers,

Paolo
