> This patchset adds the below supports for MLX5 PMD driver:
>   - Supports the metadata register Cx preserve capability query.
>   - Supports the jump action support as one of destination of array.
>   - Supports the modify action only impact on the one of destination.

> The examples for the E-Switch flow use case and result as below:
>     set sample_actions 0 port_id id 1 / end
>     flow create 0 ingress transfer pattern eth / end actions sample ratio 1 index
> 0 / jump group 1 / end
>     flow create 1 ingress transfer group 1 pattern eth / end actions
> set_mac_dst mac_addr 00:aa:bb:cc:dd:ee / port_id id 2 / end
> 
> The flow results all the matched ingress packets are mirrored
> to port id 1 and go to group 1. In the group 1, packets are modified
> with the destination mac and sent to port id 2.
