> Subject: [PATCH v3 0/5] ethdev: modify field API for multiple headers
> 
> This patch-set extend the modify field action API to support both
> multiple MPLS and GENEVE option headers.
> 
> In current API, the header type is provided by rte_flow_field_id
> enumeration and the encapsulation level (inner/outer/tunnel) is
> specified by data.level field.
> However, there is no way to specify header inside encapsulation level.
> 
> For example, for this packet:
> 
> eth / mpls / mpls / mpls / ipv4 / udp
> the both second and third MPLS headers cannot be modified using this
> API.
