From 09d4fad6e8972061fbb0e2e5ae9e686d84f57af6 Mon Sep 17 00:00:00 2001 From: Holger Schurig Date: Thu, 6 Dec 2007 13:50:30 +0100 Subject: libertas: fix data packet size errors I wondered about junk bytes at the end when using "lbsdebug +hex +host" until I noticed that firmware for the CF card sends my extranous bytes. It says "I have 20 bytes", I take 20 bytes, but the last 8 bytes of this are just data junk. Also, in the new lbs_cmd() where was a size miscalulation that made itself clear after fixing this bug.
