Hi all: This series introduces the support for rx busy polling support. This was useful for reduing the latency for a kvm guest. Instead of introducing new states and spinlocks, this series re-uses NAPI state to synchonrize between NAPI and busy polling. This grealy simplified the codes and reduce the overheads of spinlocks for normal NAPI fast path. Test was done between a kvm guest and an

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
