Dear DPDK Dev community,

I hope this is the correct mailing list for my questions, otherwise
please excuse me and let me know where my questions should be posted.

I was looking for a data structure capable to manage O-RAN Fronthaul
CUS-U headers (attached a screenshot of the header structure form a
packet analyzed with Wireshark)
but I couldn't find one.

I would like to be capable to identify the different port ids but also
the number of PRBs in the section part.

I wrote my own implementation for a simple use case (I don't take in consideration different versions and or data directions)
but it's enough for me at the moment.

What I wanted to ask is the following:
- Does a data structure for this kind of header already exists?
- If it doesn't exists is it planned?
- If it's not planned could it be of some interest?

If there is interest I would be happy to share what I developed up to
now to receive comments and/or assistance on how to make it fully
functioning.

Best regards,
Mattia
