app/testpmd: fix metadata API and Tx insertion
Previous patch introduces the Tx metadata feature, with unnecessary restrictions on data entry. It also used the metadata in txonly fwd engine only. This fix removes the data entry restrictions on metadata item. It also implements callback function to add the metadata in every Tx packet, sent by any fwd engine. Fixes: c18feafa193c ("app/testpmd: support metadata as flow rule item") Signed-off-by: Dekel Peled <dekelp@mellanox.com> Acked-by: Ori Kam <orika@mellanox.com>
