From 707985b3850f6ff168340e20b7f6b783782fb8ed Mon Sep 17 00:00:00 2001 From: David Woodhouse Date: Fri, 25 May 2007 23:41:16 -0400 Subject: [PATCH] libertas: fix big-endian associate command. Byte-swapping length fields and then passing them to memcpy() considered harmful. Signed-off-by: David Woodhouse Signed-off-by: John W.
