From 354e39dbb19f29ef28a9c2db9e55ff2a7435b35a Mon Sep 17 00:00:00 2001 From: Gertjan van Wingerde Date: Fri, 4 Dec 2009 23:47:02 +0100 Subject: [PATCH] rt2x00: Remove SKBDESC_L2_PADDED flag. With the improved L2 padding code, this flag is no longer necessary, as the rt2x00queue_remove_l2pad is capable of detecting by itself if L2 padding is applied. For received frames the RX descriptor flag is still being checked. Signed-off-by: Gertjan van Wingerde Acked-by: Ivo van Doorn Signed-off-by: John W.
