> Subject: [PATCH v4] net/mlx5: fix the NIC egress flow mismatch in switchdev
> mode
> 
> When E-Switch mode was enabled, the NIC egress flows was implicitly
> appended with source vport to match on. If the metadata register C0
> was used to maintain the source vport, it was initialized to zero
> on packet steering engine entry, the flow could be hit only
> if source vport was zero, the register C0 of the packet was not correct
> to match in the TX side, this caused egress flow misses.
> 
> This patch:
>  - removes the implicit source vport match for NIC egress flow.
>  - rejects the NIC egress flows on the representor ports at validation.
>  - allows the internal NIC egress flows containing the TX_QUEUE items in
>    order to not impact hairpins.
