The following * structure fields must not be used, except that if @flow_type includes * the %FLOW_RSS flag, then @rss_context determines which RSS context to * act on. * * For %ETHTOOL_GRXRINGS, @data is set to the number of RX rings/queues * on return. * * For %ETHTOOL_GRXCLSRLCNT, @rule_cnt is set to the number of defined * rules on return. If @data is non-zero on return then it is the * size of the rule table, plus the flag %RX_CLS_LOC_SPECIAL if the * driver supports any special location values. If that flag is not * set in @data then special location values should not be used. * * For %ETHTOOL_GRXCLSRULE, @fs.@location specifies the location of an * existing rule on entry and @fs contains the rule on return; if * @fs.@flow_type includes the %FLOW_RSS flag, then @rss_context is * filled with the RSS context ID associated with the rule. * * For %ETHTOOL_GRXCLSRLALL, @rule_cnt specifies the array size of the * user buffer for @rule_locs on entry. On return, @data is the size * of the rule table, @rule_cnt is the number of defined rules, and * @rule_locs contains the locations of the defined rules. Drivers * must use the second parameter to get_rxnfc() instead of @rule_locs. * * 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. * * For %ETHTOOL_SRXCLSRLDEL, @fs.@location specifies the location of an * existing rule on entry. * * A driver supporting the special location values for * %ETHTOOL_SRXCLSRLINS may add the rule at any suitable unused * location, and may remove a rule at a later location (lower * priority) that matches exactly the same set of flows. The special * values are %RX_CLS_LOC_ANY, selecting any location; * %RX_CLS_LOC_FIRST, selecting the first suitable location (maximum * priority); and %RX_CLS_LOC_LAST, selecting the last suitable * location (minimum priority). Additional special values may be * defined in future and drivers must return -%EINVAL for any * unrecognised value.
