ip: admin change affects intf IPv4 addr routes
Type: feature When admin status is changed on an interface, add or delete the routes for the IPv4 addresses configured on that interface. This is already being done for IPv6 interface addresses. Change-Id: Ib1e7dc49c499921dd287e075640243520ffa5589 Signed-off-by: Matthew Smith <mgsmith@netgate.com>
