Tony Nguyen says: ==================== ethtool: ice: Support for RSS settings to GTP Takeru Hayasaka enables RSS functionality for GTP packets on ice driver with ethtool. A user can include TEID and make RSS work for GTP-U over IPv4 by doing the following:`ethtool -N ens3 rx-flow-hash gtpu4 sde` In addition to gtpu(4|6), we now support gtpc(4|6),gtpc(4|6)t,gtpu(4|6)e, gtpu(4|6)u, and gtpu(4|6)d. gtpc(4|6): Used for GTP-C in IPv4 and IPv6, where the GTP header format does not include a TEID. gtpc(4|6)t: Used for GTP-C in IPv4 and IPv6, with a GTP header format that includes a TEID. gtpu(4|6): Used for GTP-U in both IPv4 and IPv6 scenarios. gtpu(4|6)e: Used for GTP-U with extended headers in both IPv4 and IPv6. gtpu(4|6)u: Used when the PSC (PDU session container) in the GTP-U extended header includes Uplink, applicable to both IPv4 and IPv6. gtpu(4|6)d: Used when the PSC in the GTP-U extended header includes Downlink, for both IPv4 and IPv6. ==================== Signed-off-by: David S.
