Sagi,
What other wins are there for this split ?
I'm considering whether its worthwhile for fc as well, but the hol
issue doesn't exist with fc. What else is being resolved ?
I've pondered it myself, which is why I didn't add it to fc as well
(would have been easy enough I think). I guess that with this the
user can limit writes compared to read by assigning less queues as
jens suggested in his patches...

I do understand if one would want to implement something like this if
there's a real benefit from the _hardware_ side, but if there isn't we
should try to keep it in the upper layers where it belongs.
Cheers,
Hannes
