Subject: IPv4LL: A state might not always exist when running the script.
X-Git-Tag: v8.1.6~1
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=378276f181314073d50399ff62e8232d0b9a8d3f;p=thirdparty%2Fdhcpcd.git

IPv4LL: A state might not always exist when running the script.

For example, we deleted existing IPv4LL addresses that dhcpcd
doesn't directly control when we obtained a DHCP lease.
