Field Documentation

   enum rte_flow_item_flex_tunnel_mode tunnel
       Specifies the flex item and tunnel relations and tells the PMD whether flex item can be used for inner,
       outer or both headers, or whether flex item presents the tunnel protocol itself.

       Definition at line 2265 of file rte_flow.h.

   struct rte_flow_item_flex_field next_header
       The next header offset, it presents the network header size covered by the flex item and can be obtained
       with all supported offset calculating methods (fixed, dedicated field, bitmask, etc).

       Definition at line 2271 of file rte_flow.h.

   struct rte_flow_item_flex_field next_protocol
       Specifies the next protocol field to match with link next protocol values and continue packet parsing
       with matching link.

       Definition at line 2276 of file rte_flow.h.

   struct rte_flow_item_flex_field* sample_data
       The fields will be sampled and presented for explicit match with pattern in the rte_flow_flex_item. There
       can be multiple fields descriptors, the number should be specified by nb_samples.

       Definition at line 2282 of file rte_flow.h.

   uint32_t nb_samples
       Number of field descriptors in the sample_data array.

       Definition at line 2284 of file rte_flow.h.

   struct rte_flow_item_flex_link* input_link
       Input link defines the flex item relation with preceding header. It specified the preceding item type and
       provides pattern to match. The flex item will continue parsing and will provide the data to flow match in
       case if there is the match with one of input links.

       Definition at line 2292 of file rte_flow.h.

   uint32_t nb_inputs
       Number of link descriptors in the input link array.

       Definition at line 2294 of file rte_flow.h.

   struct rte_flow_item_flex_link* output_link
       Output link defines the next protocol field value to match and the following protocol header to continue
       packet parsing. Also defines the tunnel-related behaviour.

       Definition at line 2300 of file rte_flow.h.

   uint32_t nb_outputs
       Number of link descriptors in the output link array.

       Definition at line 2302 of file rte_flow.h.
