This patch series introduces support for Receive Side Scaling (RSS) configuration of GTP (GPRS Tunneling Protocol) flows via the ethtool interface on virtual function (VF) interfaces in the iavf driver.
The implementation enables fine-grained traffic distribution for GTP-based mobile workloads, including GTPC and GTPU encapsulations, by extending the advanced RSS infrastructure. This is particularly beneficial for virtualized network functions (VNFs) and user plane functions (UPFs) in 5G and LTE deployments. Key features: - Adds new RSS flow segment headers and hash field definitions for GTP protocols. - Enhances ethtool parsing logic to support GTP-specific flow types. - Updates the virtchnl interface to propagate GTP RSS configuration to PF. - Extends the ICE driver to support GTP RSS configuration for VFs. Patch breakdown: 01: Add GTP RSS support in iavf driver 02..17: Extend ICE driver and protocol definitions to support GTP RSS for VFs Signed-off-by: Aleksandr Loktionov <[email protected]>
