I’m not sure I understand; it seems like somebody needs to adjust that PPL HBH
option.
Either:
PPL HBH gives total packet length
then UDP options has to know to adjust that by -2
UDP options currently takes what it gets from the IP layer length; PPL HBH
would need to know to subtract that by 2 for UDP, maybe something else for TCP
or other transports.
