From e3647801e9ef6f5267e1ef78302df6783d707981 Mon Sep 17 00:00:00 2001 From: Gabor Juhos Date: Tue, 5 Oct 2010 14:10:34 +0000 Subject: [PATCH] ramips: Allow ethernet interface to be taken down and up again Taking the ramips ethernet interface down and up again resulted in the driver not receiving any frames anymore. Fix this by correctly disabling interrupts in the hw on ifdown.
