From 53aadcc90931dfa150f76ce9a5f9e8f3e43d57df Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Tue, 27 Mar 2007 14:31:52 -0700 Subject: [PATCH] [IPV6]: Set IF_READY if the device is up and has carrier We still need to set the IF_READY flag in ipv6_add_dev for the case where all addresses (including the link-local) are deleted and then recreated. In that case the IPv6 device too will be destroyed and then recreated. In order to prevent the original problem, we simply ensure that the device is up before setting IF_READY.
