A detailed description of the format of the trailer. Presumably, for Ethernet packets with a type field, the trailer can't be found until the payload is dissected, because there's no other way to determine how large the payload is. Also, presumably, the trailer comes after any padding, and there's no FCS in these packets. _______________________________________________ tcpdump-workers mailing list tcpdump-workers@lists.tcpdump.org https://lists.sandelman.ca/mailman/listinfo/tcpdump-workers
