Patch 1 adds the support at the Kernel level, allowing the user to set a symmetric RSS hash for any flow type via: # ethtool -N|-U eth0 rx-flow-hash <flow_type> s|d|f|n symmetric Support for the new "symmetric" flag will be later sent to the "ethtool" user-space tool. Patch 2 fixes a long standing bug with the register values. The bug has been benign for now since only symmetric Toeplitz hash (Zero) has been used. Patches 3 and 4 lay some groundwork refactoring. While the first is mainly cosmetic, the second is needed since there is no more room in the previous 64-bit RSS profile ID for the symmetric attribute introduced in the next patch. Finally, patches 5 and 6 add the symmetric Toeplitz support for the ice (E800 PFs) and the iAVF drivers. --- v2: fixed a "Reviewed by" to "Reviewed-by", also need to cc maintainers.
