Subject: [PATCH 5/8] dhcp6: omit the SO_REUSEPORT option (bsc#1215692)
References: bsc#1215692
Upstream: submitted

Setting the SO_REUSEPORT socket option causes that replies are
delivered to the first process/socket bound to an [ip%dev]:port
with the effect that `wicked test dhcp6 ...` does not receive
it's replies, but the wickedd-dhcp6 (service) active on the
same interface (bsc#1215692).
