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 receivi
