So I'm not entirely clear on what that means. Did you mean "Set the
number of tcp_metrics_hash slots"? If so, that wording should be used.
Even in that case, though, what does this parameter actually *mean*? If
we're going to document the parameter (and I think we should), it would
be good to say why a user might want to change it and what effects they
would expect to see.
Care to redo with that in mind?
Thanks,
jon
