[f-nsp] Netiron AS4 capabilities

Oh yes, that looks similar. In line two, the parser complains that the expected flags do not match those of the incoming flags for the aggregator attribute.

And then, especially in line 3, does the parser then try to read from the wrong offset for routes? Whoops! At least that shouldn't happen.

Anyway, I just opened a case for MLXe. Let's see what the Extreme Engineers have to say about it. MLXe has Software Maintenance until 7/31/2025 and End of Service until 7/31/2027. And maybe they can still find a solution for both platforms.
