> The threshold of buffer replenishment for vectorized Rx burst is a constant
> value (64). If the size of Rx queue is comparatively small, device could run out
> of buffers. For example, if the size of Rx queue is 128, buffers are
> replenished only twice per a wraparound. This can cause jitter in receiving
> packets and the jitter can cause unnecessary retransmission for TCP
> connections.
