This patch series extends busy polling range to tunnels devices, and allows NAPI drivers to support busy polling with trivial changes.
No need to provide ndo_busy_poll() method and extra synchronization between ndo_busy_poll() and normal napi->poll() method. This was proven very difficult and bug prone. mlx5 driver is changed to support busy polling using this new method, and a second mlx5 patch adds napi_complete_done() support and proper SNMP accounting. bnx2x and mlx4 drivers are converted to new infrastructure, reducing kernel bloat and improving performance. Eric Dumazet (9): net: better skb->sender_cpu and skb->napi_id cohabitation mlx4: mlx4_en_low_latency_recv() called with BH disabled net: un-inline sk_busy_loop() net: allow BH servicing in sk_busy_loop() net: network drivers no longer need to implement ndo_busy_poll() mlx5: add busy polling support mlx5: support napi_complete_done() bnx2x: remove bnx2x_low_latency_recv() support mlx4: remove mlx4_en_low_latency_recv() drivers/net/ethernet/broadcom/bnx2x/bnx2x.h | 113 ------------------- drivers/net/ethernet/broadcom/bnx2x/bnx2x_cmn.c | 46 +------- drivers/net/ethernet/broadcom/bnx2x/bnx2x_cmn.h | 7 -- drivers/net/ethernet/broadcom/bnx2x/bnx2x_main.c | 3 - drivers/net/ethernet/mellanox/mlx4/en_ethtool.c | 17 --- drivers/net/ethernet/mellanox/mlx4/en_netdev.c | 40 ------- drivers/net/ethernet/mellanox/mlx4/en_rx.c | 15 +-- drivers/net/ethernet/mellanox/mlx4/mlx4_en.h | 126 ---------------------- drivers/net/ethernet/mellanox/mlx5/core/en.h | 2 +- drivers/net/ethernet/mellanox/mlx5/core/en_main.c | 6 ++ drivers/net/ethernet/mellanox/mlx5/core/en_rx.c | 16 +-- drivers/net/ethernet/mellanox/mlx5/core/en_txrx.c | 11 +- include/linux/netdevice.h | 9 -- include/linux/skbuff.h | 3 - include/net/busy_poll.h | 45 +------- net/core/dev.c | 91 ++++++++++++---- 16 files changed, 98 insertions(+), 452 deletions(-) -- 2.6.0.rc2.230.g3dd15c0 -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
