From: Ivo van Doorn Date: Sat, 13 Oct 2007 14:26:27 +0000 (+0200) Subject: [PATCH] rt2x00: SW diversity should default to antenna B X-Git-Tag: v2.6.25-rc1~1162^2~691 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=39e75857d08fe35ffad4dd9004580acf0d725b75;p=linux-2.6 [PATCH] rt2x00: SW diversity should default to antenna B Although ANTENNA_SW_DIVERSITY should never be send to the driver, we should still handle it to prevent bugs. But instead of defaulting to ANTENNA_HW_DIVERSITY we should default to ANTENNA_B instead. Signed-off-by: Ivo van Doorn Signed-off-by: John W. Linville Signed-off-by: David S.
