net/mlx5e: Add trace point for neigh used value update
Allow tracing result of neigh used value update task that is executed periodically on workqueue. Usage example: ># cd /sys/kernel/debug/tracing ># echo mlx5:mlx5e_tc_update_neigh_used_value >> set_event ># cat trace ... kworker/u48:4-8806 [009] ...1 55117.882428: mlx5e_tc_update_neigh_used_value: netdev: ens1f0 IPv4: 1.1.1.10 IPv6: ::ffff:1.1.1.10 neigh_used=1 Added corresponding documentation in Documentation/networking/device-driver/mellanox/mlx5.rst Signed-off-by: Vlad Buslov <vladbu@mellanox.com> Reviewed-by: Dmytro Linkin <dmitrolin@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>
