0 means "there is no FCS in the packet data", 4 means "there is an FCS in the packet data", -1 means "I don't know whether there's an FCS in the packet data, guess based on the packet size". Assume that Ethernet encapsulated inside other protocols has no FCS, by having the "eth" dissector assume that (and not check for an Ethernet pseudo-header). Have "ethertype()" take an argument giving the FCS size; pass 0 when appropriate. Fix up Wiretap routines to set the pseudo-header. This means we no longer use the "generic" seek-and-read routine, so get rid of it. svn path=/trunk/; revision=8574
