From 7276d5d743d775388bf382cd7bdea1a14e486d32 Mon Sep 17 00:00:00 2001 From: Daniel Borkmann Date: Tue, 23 Apr 2013 00:39:30 +0000 Subject: packet: minor: convert status bits into shifting format This makes it more readable and clearer what bits are still free to use. The compiler reduces this to a constant for us anyway. Signed-off-by: Daniel Borkmann Acked-by: Willem de Bruijn Signed-off-by: David S.
