Hi all: This series introduces the support for rx busy polling support. This was useful for reduing the latency for a kvm guest. Patch 1-2 introduces helpers which is used for rx busy polling. Patch 3 implement the main function. Test was done between a kvm guest and an external host. Two hosts were connected through 40gb mlx4 cards. With both busy_poll and busy_read are set to 50 in guest, 1

It looks like there's no need for those two fields: - Unless there's a failure for the first refill try, rq->max should be always equal to the vring size. - rq->num is only used to determine the condition that we need to do the refill, we could check vq->num_free instead. - rq->num was required to be increased or decreased explicitly after each get/put which results a bad API. So this...
