> Subject: [PATCH] net/mlx5: fix VLAN/DECAP actions not work in mirror flow
> 
> Due to hardware limitations the VLAN push/pop and Decap actions following
> the sample action are supported in the FDB Tx steering domain only, the
> flows with incorrect action order for other domains are rejected by rdma-
> core.
> 
> To provide the action order requested in RTE flow this patch checks for the
> VLAN or Decap precedence to the sample action and moves the VLAN or
> Decap actions into the next flow in the new table and adds the jump action in
> the prefix sample flow.
> 
> This patch also adds the validation for these combination actions.
