-- This operation updates the bandwidth rate limits of a gateway. You can
-- update both the upload and download bandwidth rate limit or specify only
-- one of the two. If you don\'t set a bandwidth rate limit, the existing
-- rate limit remains.
--
-- By default, a gateway\'s bandwidth rate limits are not set. If you
-- don\'t set any limit, the gateway does not have any limitations on its
-- bandwidth usage and could potentially use the maximum available
-- bandwidth.
--
-- To specify which gateway to update, use the Amazon Resource Name (ARN)
-- of the gateway in your request.
