Subject: [BUG] selftests/net: icmp_redirect.sh: 12 out of 40 test result with
 [FAIL]

Hi,

With the commit v6.8-11167-g4438a810f396 in vanilla torvalds tree, there seem to be problems with
the icmp_redirect.sh tests.

The iproute2-next tools were used, commit 7a6d30c95da9.

These errors are not introduced with this commit, but were already present at least in 6.8-rc7.

Hope this helps.
