My guess is it is because of the 16 byte default limit on the header length, as Guy mentioned a couple days ago. > Should we add that the padding is done with '\0' bytes ? As far as encodings typically go, if the padding bytes are always discarded, it does not make difference. But it will not hurt to say the customary "MBZ". -- Denis Ovsienko _______________________________________________ tcpdump-workers mailing list tcpdump-workers@lists.tcpdump.org https://lists.sandelman.ca/mailman/listinfo/tcpdump-workers
