Hi, I Need to register two DLTs they would be: DLT_MTP2_MULTISTANDARD that will have a one byte pseudo header of which the MS bit indicates the direction the next three bits are reserved and must be set to zero in writing the last nibble is used to indicate the standard used for mtp3 packets transported (0000=itu, 0001=ansi, 0010=japan, 0011=china, other values are reserved for future extensions), readers must ignore the contents of the three reserved bits.

Is a capture likely to have a mix of packets for different MTP3 standards? And are there likely to be more types in the future?
If not, should we just have multiple DLT_MTP2_ and DLT_MTP3_ values? - This is the tcpdump-workers list. Visit https://cod.sandelman.ca/ to unsubscribe.
