Subject: [PATCH iwl-next v10 4/5] ice: Extend PTYPE bitmap coverage for GTP encapsulated flows
From: Przemek Kitszel <przemyslaw.kitszel@...el.com>
Consolidate updates to the Protocol Type (PTYPE) bitmap definitions
across multiple flow types in the Intel ICE driver to support GTP
(GPRS Tunneling Protocol) encapsulated traffic.
Enable improved Receive Side Scaling (RSS) configuration for both user
and control plane GTP flows.
Cover a wide range of protocol and encapsulation scenarios, including:
- MAC OFOS and IL
- IPv4 and IPv6 (OFOS, IL, ALL, no-L4)
- TCP, SCTP, ICMP
- GRE OF
- GTPC (control plane)
Expand the PTYPE bitmap entries to improve classification and
distribution of GTP traffic across multiple queues, enhancing
performance and scalability in mobile network environments.
