net/mlx5e: Add trace point for neigh update
Allow tracing neigh state during neigh update task that is executed on
workqueue and is scheduled by neigh state change event.
Usage example:
># cd /sys/kernel/debug/tracing
># echo mlx5:mlx5e_rep_neigh_update >> set_event
># cat trace
...
kworker/u48:7-2221 [009] ...1 1475.387435: mlx5e_rep_neigh_update:
netdev: ens1f0 MAC: 24:8a:07:9a:17:9a IPv4: 1.1.1.10 IPv6: ::ffff:1.1.1.10 neigh_connected=1
Added corresponding documentation in
