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-xor
Support for the new "symmetric-xor" 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 (asymmetric) 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.
---
v5: move sanity checks from ethtool/ioctl.c to ice's and iavf's rxfnc
drivers entries (patches 5 and 6).
v4: add a comment to "#define RXH_SYMMETRIC_XOR" (in uapi/linux/ethtool.h)
v3: rename "symmetric" to "symmetric-xor" and drop "Fixes" tag in patch 2.
v2: fixed a "Reviewed by" to "Reviewed-by", also need to cc maintainers.
