> Subject: [PATCH v2 4/6] net/mlx5: conditional hairpin auto bind
> 
> In single port hairpin mode, after the queues are configured during start up.
> The binding process will be enabled automatically in the port start phase and
> the default control flow for egress will be created.
> 
> When switching to two ports hairpin mode, the auto binding process should be
> skipped if there is no TX queue with the peer RX queue on the same device,
> and it should be skipped also if the queues are configured with manual bind
> attribute.
> 
> If the explicit TX flow rule mode is configured or hairpin is between two ports,
> the default control flows for TX queues should not be created.
