Rte_flow Match with Comparison Result
summary
Adds an RTE_FLOW compare item that matches fields with operators (=, !=, <, <=, >, >=) against another field or an immediate value, implemented in the template API and present in mlx5 PMD for ConnectX‑7/BlueField‑3+; supports up to 32‑bit widths, limited initial field set (tags, metadata, TCP/IP lengths, random, value), and only one comparison item per template with no mixing with other match items; practical examples include TCP port > N and length checks to detect no‑payload packets, and it is implemented and usable today.
