[f-nsp] Netiron AS4 capabilities

[Bogdan Rotariu]

Ok, I can totally replicate the issue using Mikrotik's CHR latest 7.11beta2. Session between a CHR and a CER2024 closes with same error "Error: Invalid AGGREGATOR attribute length 8”. If anyone would like to do a test I would appreciate that.

Unfortunately I cannot convince Mikrotik that they have a bug and till now I cannot see anyone else on the forum or on their discord server that are affected by this
