Subject: [PATCH net-next 0/6] Support symmetric RSS (Toeplitz) hash

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.
