Linux shaping packet loss

Won't say I'm an expert with TC, but anytime I see packet loss on an 
interface I always check the interface itself...10% packet loss is 
pretty much what you would get if there was a duplex problem. I always 
try to hard set my interfaces on both the Linux machines and Switches.
