From 78b8f3b0ddb061af1e3907f9c4bca76eae39f79f Mon Sep 17 00:00:00 2001 From: Gertjan van Wingerde Date: Sat, 8 May 2010 23:40:20 +0200 Subject: [PATCH] rt2x00: Don't check whether hardware crypto is enabled when reading RXD. We should simply follow what the hardware told us it has done. Signed-off-by: Gertjan van Wingerde Acked-by: Ivo van Doorn Signed-off-by: John W.
