Why is pause not supported with NCSI? There are two modes for
Pause. It can be negotiated, or it can be forced. Negotiation cannot
be used, there is not a link peer as such, but it should be possible
to force the configuration.

I am however assuming that pause frames do get forwarded by the other
end of the link. Does the NCSI standard say anything about that?
