    net: ethtool: extend RXNFC API to support RSS spreading of filter matches · 84a1d9c4
    Edward Cree authored
    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.
