+- * genl_register_family_with_ops - register a generic netlink family
+- * @family: generic netlink family
+- * @ops: operations to be registered
+- * @n_ops: number of elements to register
+- *
+- * Registers the specified family and operations from the specified table.
+- * Only one family may be registered with the same family name or identifier.
+- *
+- * The family id may equal GENL_ID_GENERATE causing an unique id to
+- * be automatically generated and assigned.
+- *
+- * Either a doit or dumpit callback must be specified for every registered
+- * operation or the function will fail. Only one operation structure per
+- * command identifier may be registered.
+- *
+- * See include/net/genetlink.h for more documenation on the operations
+- * structure.
+- *
+- * This is equivalent to calling genl_register_family() followed by
+- * genl_register_ops() for every operation entry in the table taking
+- * care to unregister the family on error path.
+- *
+- * Return 0 on success or a negative error code.
