Yes; the struct ethtool_rxnfc kerneldoc has: * For %ETHTOOL_SRXCLSRLINS, @fs specifies the rule to add or update. * @fs.@location either specifies the location to use or is a special * location value with %RX_CLS_LOC_SPECIAL flag set. On return, * @fs.@location is the actual rule location. If @fs.@flow_type * includes the %FLOW_RSS flag, @rss_context is the RSS context ID to * use for flow spreading traffic which matches this rule. The value * from the rxfh indirection table will be added to @fs.@ring_cookie * to choose which ring to deliver to. I am also preparing a patch to add this info to the ethtool man page.
