From a02a68ea2bdbb7cac95eaf13ff27a417e0a2fac1 Mon Sep 17 00:00:00 2001 From: Gabor Juhos Date: Mon, 28 Jun 2010 17:23:28 +0000 Subject: [PATCH] rt2x00: cleanup patches Remove 601-rt2x00-remove-mcu-requests-for-soc.patch as an equivalent patch is already included in upstream. Add 601-rt2x00-fix-hang-on-ifdown.patch which is not suitable for upstream inclusion but fixes a hang on ifdown under some circumstances and thus also fixes AP mode operation in OpenWRT.
