X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2de751b3691642151a4fdc49e444d6b4dc364e98;p=thirdparty%2Fdhcpcd.git

IPv4: Ignore DHCP state when building routes (#557)

* IPv4: Ignore DHCP state when building routes

As this will change periodically.
We only care if the state (address) has been added.

Fixes #440 thanks to JognSmit.
