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.
