From eb62efd287fe6e12d18083287e38e4a811c28256 Mon Sep 17 00:00:00 2001 From: Jesse Brandeburg Date: Fri, 17 Apr 2009 20:44:36 +0000 Subject: [PATCH] e1000: init link state correctly As reported by Andrew Lutomirski All the intel wired ethernet drivers were calling netif_carrier_off and netif_stop_queue (or variants) before calling register_netdevice This is incorrect behavior as was pointed out by davem, and causes ifconfig and friends to report a strange state before first link after the driver was loaded. This apparently confused *some* versions of networkmanager. Andy tested this for e1000e and confirmed it was working for him.
