RDMA/nldev: Added configuration of RDMA dynamic interrupt moderation to netlink
Added parameter in ib_device for enabling dynamic interrupt moderation so
that it can be configured in userspace using rdma tool.
In order to set adaptive-moderation for an ib device the command is:
rdma dev set [DEV] adaptive-moderation [on|off]
Please set on/off.
rdma dev show
0: mlx5_0: node_type ca fw 16.26.0055 node_guid 248a:0703:00a5:29d0
sys_image_guid 248a:0703:00a5:29d0 adaptive-moderation on
rdma resource show cq
dev mlx5_0 cqn 0 cqe 1023 users 4 poll-ctx UNBOUND_WORKQUEUE
