From e25c4bb913e54d729631ba7eb50daf1d9aacbef6 Mon Sep 17 00:00:00 2001 From: Ivo van Doorn Date: Sat, 27 Oct 2007 13:39:28 +0200 Subject: [PATCH] rt2x00: Disable RX when switching antenna Antenna switching will be ignored when RX is enabled during the switch. Make sure we disable the RX during the switch and don't forget to reenable it later. Signed-off-by: Ivo van Doorn Signed-off-by: John W. Linville Signed-off-by: David S.
