From 17f8be7dafce4e4b92fbe7bfec605944df290546 Mon Sep 17 00:00:00 2001 From: Ido Schimmel Date: Sat, 3 Dec 2016 16:45:04 +0100 Subject: [PATCH] rocker: Register FIB notifier before creating ports We can miss FIB notifications sent between the time the ports were created and the FIB notification block registered. Instead of receiving these notifications only when they are replayed for the FIB notification block during registration, just register the notification block before the ports are created.
