I don't think this should be adjustable.

I assume you tested this in conjunction with rx batching patch - what
fill level values did you use to see throughput improvement? How
(un)responsive was serial/ssh connection to the machine?

I have a patch internally which removes the replenishment tasklet and
I wonder how will it behave with rx batching then, hmm..
