[PATCH v4 0/5] ethdev: modify field API for multiple headers

[Michael Baum <michaelba@nvidia.com>]

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.
