ibmveth: batch rx buffer replacement
At the moment we try and replenish the receive ring on every rx interrupt.
We even have a pool->threshold but aren't using it.
To limit the maximum latency incurred when refilling, change the threshold
from 1/2 to 7/8 and reduce the largest rx pool from 768 buffers to 512 which
should be more than enough.
