Subject: [net-next 09/15] net/mlx5: Reduce number of vport lookups passing vport pointer instead of index
From: Jiri Pirko <jiri@...dia.com>
During devlink port init/cleanup and register/unregister calls, there
are many lookups of vport. Instead of passing vport_num as argument to
functions, pass the vport struct pointer directly and avoid repeated
lookups.
