Allow the user to set the symmetric Toeplitz hash function via:
# ethtool -X eth0 hfunc toeplitz symmetric-xor
All existing RSS configurations will be converted to symmetric unless they
have a non-symmetric field (other than IP src/dst and L4 src/dst ports)
used for hashing. The driver will reject a new RSS configuration if such
a field is requested.
The hash function in the E800 NICs is set per-VSI and a specific AQ
command is needed to modify the hash function. Use the AQ command to
enable setting the symmetric Toeplitz RSS hash function for any VSI
in the new ice_set_rss_hfunc().
When the Symmetric Toeplitz hash function is used, the hardware sets the
input set of the RSS (Toeplitz) algorithm to be the XOR of the fields
index by HSYMM and the fields index by the INSET registers. We use this
to create a symmetric hash by setting the HSYMM registers to point to
their counterparts in the INSET registers:
HSYMM [src_fv] = dst_fv;
HSYMM [dst_fv] = src_fv;
where src_fv and dst_fv are the indexes of the protocol's src and dst
fields.
