-- | 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.
