From 44bcc068168815cfc0bb9f1c8b692bef67c0e471 Mon Sep 17 00:00:00 2001 From: "Andrey V. Elsukov" Date: Sat, 9 Jun 2018 09:57:14 +0000 Subject: [PATCH] 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).
