ice: implement GTP RSS context tracking and configuration

2025-11-06T22:19:43Z

This commit implements the core RSS context management and configuration logic for GTP (GTPU) protocol support in VF RSS operations. Key implementation features: - GTPU hash context management with pre/post processing functions - Context index calculation and mapping for different GTPU scenarios - Integration with main RSS configuration flow via wrapper functions - Support for IPv4/IPv6 GTPU RSS configurations - Rollback mechanism for handling RSS rule conflicts - Hash context reset and cleanup functionality The implementation provides comprehensive GTPU RSS support by: 1. Adding ice_add_rss_cfg_pre_gtpu() for preprocessing GTPU contexts 2. Adding ice_add_rss_cfg_post_gtpu() for postprocessing configurations 3. Adding ice_calc_gtpu_ctx_idx() for context index calculation 4. Integrating GTPU logic into ice_add_rss_cfg_wrap() and ice_rem_rss_cfg_wrap() 5. Supporting context tracking in VF hash_ctx structures This completes the GTP RSS infrastructure enabling VFs to configure RSS hashing on GTP-encapsulated traffic.

ice: add virtchnl definitions and static data for GTP RSS

2025-11-06T22:19:43Z

Add virtchnl protocol header and field definitions for advanced RSS configuration including GTPC, GTPU, L2TPv2, ECPRI, PPP, GRE, and IP fragment headers. - Define new virtchnl protocol header types - Add RSS field selectors for tunnel protocols - Extend static mapping arrays for protocol field matching - Add L2TPv2 session ID and length+session ID field support This provides the foundational definitions needed for VF RSS configuration of tunnel protocols.

ice: finish virtchnl.c split into rss.c

2025-08-27T07:20:06Z

Move functions out of virt/virtchnl.c to virt/rss.c. Same "git tricks" used as for the split into virt/queues.c that is immediately preceding this split. Signed-off-by: Przemek Kitszel Signed-off-by: Tony Nguyen

ice: extract virt/rss.c: cleanup - p2

2025-08-27T07:20:06Z

Remove remaining portion of the stuff that stays within virtchnl.c, (separate commits to have nicer, removal-only, history). Signed-off-by: Przemek Kitszel Signed-off-by: Tony Nguyen

ice: extract virt/rss.c: cleanup - p1

2025-08-27T07:20:06Z

Start removing stuff from virt/rss.c that will be kept in the main virtchnl file. Signed-off-by: Przemek Kitszel Signed-off-by: Tony Nguyen

ice: split RSS stuff out of virtchnl.c - tmp rename

2025-08-27T07:20:05Z

Temporary rename of virtchnl.c into rss.c In order to split virtchnl.c in a way that makes it much easier to still blame new file, we do it via multiple git steps. Signed-off-by: Przemek Kitszel Signed-off-by: Tony Nguyen
