Author: ae Date: Wed Jun 13 07:17:10 2018 New Revision: 335033 URL: https://svnweb.freebsd.org/changeset/base/335033 Log: MFC r334875: Explicitly change the link state when we assingn an address. Since we are setting IFF_UP flag on SIOCSIFADDR, it is possible, that after this link state information still not initialized properly. This leads to problems with routing, since now interface has IFCAP_LINKSTATE capability and a route is considered as working only when interface's link state is in LINK_STATE_UP (see RT_LINK_IS_UP() macro).
