Subject: Enable callers to pass the source IP of an IPv4 route when using
X-Git-Url: https://git.archive.openwrt.org/?p=project%2Fnetifd.git;a=commitdiff_plain;h=19c53807d9dc62782d03c5564630ed1bcb953cd8

Enable callers to pass the source IP of an IPv4 route when using
proto_add_ipv4_route(). This is useful with for example DHCP in a multihomed
scenario, as it provides an easy way to match default routes with the correct IP
address. One use case for this are applications that monitor the state of the
WAN port, and the WAN port is assigned multiple addresses.
