+ * 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.
