cxgb_busy_poll, corresponding to ndo_busy_poll, gets called by the socket waiting for data. With busy_poll enabled, improvement is seen in latency numbers as observed by collecting netperf TCP_RR numbers. Below are latency number, with and without busy-poll, in a switched environment for a particular msg size: netperf command: netperf -4 -H <ip> -l 30 -t TCP_RR -- -r1,1 Latency without busy-poll: ~16.25 us Latency with busy-poll : ~08.79 us Based on original work by Kumar Sanghvi <kumaras@chelsio.com> Signed-off-by: Hariprasad Shenai <hariprasad@chelsio.com> Signed-off-by: David S.
