+ * @cmd: Specific command number - %ETHTOOL_GRSSH or %ETHTOOL_SRSSH
+ * @rss_context: RSS context identifier.
+ * @indir_size: On entry, the array size of the user buffer for the
+ *     indirection table, which may be zero, or (for %ETHTOOL_SRSSH),
+ *     %ETH_RXFH_INDIR_NO_CHANGE.  On return from %ETHTOOL_GRSSH,
+ *     the array size of the hardware indirection table.
+ * @key_size: On entry, the array size of the user buffer for the hash key,
+ *     which may be zero.  On return from %ETHTOOL_GRSSH, the size of the
+ *     hardware hash key.
+ * @rsvd:      Reserved for future extensions.
+ * @rss_config: RX ring/queue index for each hash value i.e., indirection table
+ *     of @indir_size __u32 elements, followed by hash key of @key_size
+ *     bytes.
+ *
+ * For %ETHTOOL_GRSSH, a @indir_size and key_size of zero means that only the
+ * size should be returned.  For %ETHTOOL_SRSSH, an @indir_size of
+ * %ETH_RXFH_INDIR_NO_CHANGE means that indir table setting is not requested
+ * and a @indir_size of zero means the indir table should be reset to default
+ * values.
