Description

Joyent found this as "OS-203", and it was fixed in the Joyent Illumos batch.

Joyent's experience suggests that the TCP constant ISS_INCR be an ndd(1M) tunable instead.

I'm guessing in this case "ndd" really expands to the Brussels stuff? (if it doesn't, should it?)

Brussels is more for NIC tunables, ipadm might be a better spot (though I'm a bit skeptical). I don't think anything was really done to address tcp or udp tunables yet.

Ah, right. We have no home for protocol tunables that aren't per-address or per interfaces except ndd. I thought Brussels II had given a new home to all of them.
