Subject: [PATCH] selftests: Update fib_nexthop_multiprefix to handle missing ping6
Date: Tue, 17 Sep 2019 10:30:35 -0700 [thread overview]
Message-ID: <20190917173035.19753-1-dsahern@kernel.org> (raw)
From: David Ahern <dsahern@gmail.com>
Some distributions (e.g., debian buster) do not install ping6. Re-use
the hook in pmtu.sh to detect this and fallback to ping.
Fixes: 735ab2f65dce ("selftests: Add test with multiple prefixes using single nexthop")
Signed-off-by: David Ahern <dsahern@gmail.com>
