net: ethtool: extend RXNFC API to support RSS spreading of filter matches
We use a two-step process to configure a filter with RSS spreading. First,
the RSS context is allocated and configured using ETHTOOL_SRSSH; this
returns an identifier (rss_context) which can then be passed to subsequent
invocations of ETHTOOL_SRXCLSRLINS to specify that the offset from the RSS
indirection table lookup should be added to the queue number (ring_cookie)
when delivering the packet. Drivers for devices which can only use the
indirection table entry directly (not add it to a base queue number)
should reject rule insertions combining RSS with a nonzero ring_cookie.
