[PATCH mlx5-next 11/13] net/mlx5: Forward QP/WorkQueues resource events

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Allow forwarding QP and WQ events to mlx5_core interfaces, e.g. mlx5_ib

Use mlx5_notifier_register/unregister in qp.c in order to allow seamless
transition of qp.c to infiniband subsystem.
