ethtool: Support for configurable RSS hash function
This ethtool patch adds support to set and get the current RSS hash
function for the device through the new hfunc mask field in the
ethtool_rxfh struct. Kernel supported hash function names are queried
with ETHTOOL_GSTRINGS - each string is corresponding with a bit in hfunc
mask according to its index in the string-set.
