Subject: [PATCH net-next 1/2] selftests: Disable dad for ipv6 in fcnal-test.sh
Date: Tue,  9 Sep 2025 20:58:27 -0600	[thread overview]
Message-ID: <20250910025828.38900-1-dsahern@kernel.org> (raw)

Constrained test environment; duplicate address detection is not needed
and causes races so disable it.
