Subject: [PATCH] selftests: net: udpgro_fwd.sh: explicitly checking the available ping feature
Git-commit: 5e75d0b215b868337e7a193f28a543ec00e858b1
Patch-mainline: v5.16
References: git-fixes
As Paolo pointed out, the result of ping IPv6 address depends on
the running distro. So explicitly checking the available ping feature,
as e.g. do the bareudp.sh self-tests.
