Thanks for the PR. Could you please check if it is possible to add interoperability tests with existing tools or libraries, such as lldpd, to the unit tests. |

Hi Nils, by interoperability tests you mean: Making a real environment -> capturing everything -> writing tests based on the pcaps to make sure it gets parsed correctly? Like the last test ( |

No, those tests are also important, but if possible I have something like this in mind. Start lldpd with a certain configuration in a subprocess, In this way we can automatically verify the interaction with a real world application/libray. |

Regarding the interoperability tests, it doesn't matter if not all IDs are supported. At least we get an overall good coverage on AI generated code. |

Hi everyone,
This PR adds 15 new org-specific TLVs for IEEE 802.1Q:
First, I wanted to implement only the ones that I needed (VLAN stuff), but then decided to implement all of them.
The code has been written mostly by AI. I've reviewed and corrected every line of it.
