Subject: [PATCH] b44: fix carrier detection on bind
Date: Tue, 12 Oct 2010 02:42:30 +0400 [thread overview]
Message-ID: <1286836950-3161-1-git-send-email-fercerpav@gmail.com> (raw)
For carrier detection to work properly when binding the driver with a cable
unplugged, netif_carrier_off() should be called after register_netdev(),
not before.

Without this it's quite annoying to boot a laptop without ethernet
connection as the userspace is getting confused and can even add a default
route through a non-functional interface (when it's configured to use
static ip).
