Subject: network/dhcp6: return earlier if no lease acquired
X-Git-Tag: v256-rc1~260
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d4dae4c24388f6bff8f9015d7d266376d8d8b9c6;p=thirdparty%2Fsystemd.git

network/dhcp6: return earlier if no lease acquired

Previously, even If an interface has not acquired a DHCPv6 lease,
networkd logs a misleading message:
===
Apr 09 10:44:57 systemd-networkd[3970750]: veth99: DHCPv6 lease lost
===
The function should do nothing when no lease acquired. Let's return
earlier and suppress the log message.
