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.
