Subject: [PATCH for-next V2 13/15] net/mlx5: Add multi dest support
From: Mark Bloch <markb@...lanox.com>
Currently when calling mlx5_add_flow_rule we accept
only one flow destination, this commit allows to pass
multiple destinations.
This change forces us to change the return structure to a more
flexible one. We introduce a flow handle (struct mlx5_flow_handle),
it holds internally the number for rules created and holds an array
where each cell points the to a flow rule.
>From the consumers (of mlx5_add_flow_rule) point of view this
change is only cosmetic and requires only to change the type
of the returned value they store.
>From the core point of view, we now need to use a loop when
allocating and deleting rules (e.g given to us a flow handler).
