RE: Q: is framing-capabilities value=0 legal

Thank you Mr. Goyret,

	I hope I paraphrase your response correctly to say that Fr-cap=0
is allowable and its meaning is "I will not initiate", and it may even
be common from an LNS.


	But even if I see your meaning correctly, that still does not
help me in my situation. I'm the LNS, and I am receiving Fr-Cap=0 from
the LAC. The LAC I am dealing with has an obvious bug in that it's
Fr-Cap setting is configurable but it ignores the configuration and
always sends 0. Yet still, this is a popular LAC and I want to
interoperate with it.

	From my LNS's perspective... should I be generous in what I
accept, or is there a reason I must abort the connection?
