* enic: add low latency socket busy_poll supportGovindarajulu Varadarajan2014-06-23
| | | | | | | | | | | | | | | | | | | This patch adds support for low latency busy_poll. * Introduce drivers ndo_busy_poll function enic_busy_poll, which is called by socket waiting for data. * Introduce locking between napi_poll nad busy_poll * enic_busy_poll cleans up all the rx pkts possible. While in busy_poll, rq holds the state ENIC_POLL_STATE_POLL. While in napi_poll, rq holds the state ENIC_POLL_STATE_NAPI. * in napi_poll we return if we are in busy_poll. Incase of INTx & msix, we just service wq and return if busy_poll is going on. Signed-off-by: Govindarajulu Varadarajan <_govind@gmx.com> Signed-off-by: David S. Miller <davem@davemloft.net>
