From 808a6ab903d17969e284cadd416f8f126b40648c Mon Sep 17 00:00:00 2001 From: juhosg 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.
