From 5e75d0b215b868337e7a193f28a543ec00e858b1 Mon Sep 17 00:00:00 2001 From: Jianguo Wu Date: Fri, 31 Dec 2021 10:01:08 +0800 Subject: selftests: net: udpgro_fwd.sh: explicitly checking the available ping feature 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.
