From 546add79468183f266c75c632c96e4b0029e0d96 Mon Sep 17 00:00:00 2001 From: Krzysztof Piotr Oledzki Date: Wed, 6 Oct 2010 14:28:22 -0700 Subject: bonding: reread information about speed and duplex when interface goes up When an interface was enslaved when it was down, bonding thinks it has speed -1 even after it goes up. This leads into selecting a wrong active interface in active/backup mode on mixed 10G/1G or 1G/100M environment. before: bonding: bond0: link status definitely up for interface eth5, 100 Mbps full duplex. bonding: bond0: link status definitely up for interface eth0, 100 Mbps full duplex. after: bonding: bond0: link status definitely up for interface eth5, 10000 Mbps full duplex. bonding: bond0: link status definitely up for interface eth0, 1000 Mbps full duplex.
