Hi,

I am trying to find the feasibility of implementing GTP-U tunneling
Protocol using P4. The header has a message length, followed by extension
headers which are optional. The extension headers are identified using the
next extension header field(Not TLV type).

I did not understand how this could be implemented using P4. Please let me
know your suggestions regarding the implementation of the same.

... Contents Next extension header


Regards,
Mohan
