TCP port space is just the beginning but then these features
didn't show up all at once in the kernel either. Instead of
evolving iWARP implementation, we can't even take a baby step
and fix a flaw that exists in the current kernel. Why are we
"replicating" everything offered by the host stack instead of
hooking in? It does not sound like good engineering to me.
