Well, just looking at it, I presume you're getting an error on send when you
send over your raw socket.  If so, whats the error you're getting?  If you're
not getting an error, then you're dropping it somewhere in the stack.  After you
loose the data in question, what do youre /proc/net/dev and ethtool stats look
like?
