Subject: IPv4LL: A state might not always exist when running the script.
X-Git-Tag: v9.0.0~75
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e933e7d18b4dbf2efce2e8652eff31d8bea0791f;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.
