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. Latest patch, adding generic support, adds a new requirement : -free_netdev() and netif_napi_del() must be called from process context. Since this might not be the case in some drivers, we might have to either : fix the non conformant drivers (by disabling busy polling on them) or revert this last patch. ==================== Signed-off-by: David S.
