I salute you for having gotten into whether the code is compliant. But, I did write spend way too much of my life writing https://datatracker.ietf.org/doc/rfc9008/ to deal with the perception that RPL networks had to violate 8200. I know that Linux does not (yet) deal with all the minutia in 9008. I wish that I had time to fix that. --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQFFBAEBCgAvFiEEbsyLEzg/qUTA43uogItw+93Q3WUFAmU5NdIRHG1jckBzYW5k ZWxtYW4uY2EACgkQgItw+93Q3WU2zAf/cRuEHXQxSDAE+5gPXxTzLCbFoHAfIBvu prznbJWTnb+eU8edAt4v+KEF+0bdgnU9ipcumA5iqGua5jb34t4U7mb+LHdDxP0X 3bRM1QL1tS3khF8g3v+MZdhO+MkHHmjeAP6VCS8Ktljg8OvTI4P5AKHBLdo+28qa VNwnaaKG7vRoiNKMiPuiNQ38ECqwYFrsBrOnqYTQFyHebREci5UR91bFj1dX+Hen /FbaqsBpTfZSHsmKRF7LSfUS0TMlw3PH/2TNJRUn+GHxN1ODA3ou0+RBrTNSTge2 4ZV18sqDW+FSOM47ZPWSZPDmm5oatMmrMzf5DhFfLyOVBYFhXAE+Cw== =KOKq -----END PGP SIGNATURE----- --=-=-=--
