ice: add flow parsing for GTP and new protocol field support
Introduce new protocol header types and field sizes to support GTPU, GTPC tunneling protocols. - Add field size macros for GTP TEID, QFI, and other headers - Extend ice_flow_field_info and enum definitions - Update hash macros for new protocols - Add support for IPv6 prefix matching and fragment headers This patch lays the groundwork for enhanced RSS and flow classification capabilities.
