Yes, I did not intend any parsing either: the SLLvx should end with the ethtype 
(the one that occurs right after the MAC addresses in Ethernet). But I was just 
pointing out that it is a pity that SSLv1 and SSLv2 only keep the source MAC 
address when all physical interfaces in a system are Ethernet. Why not keep the 
whole MAC header ?
