From: juhosg Date: Tue, 5 Oct 2010 14:10:34 +0000 (+0000) Subject: ramips: Allow ethernet interface to be taken down and up again X-Git-Url: https://git.rohieb.name/openwrt.git/commitdiff_plain/808a6ab903d17969e284cadd416f8f126b40648c?ds=sidebyside 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.
