-- This operation returns the bandwidth rate limits of a gateway. By
-- default, these limits are not set, which means no bandwidth rate
-- limiting is in effect.
--
-- This operation only returns a value for a bandwidth rate limit only if
-- the limit is set. If no limits are set for the gateway, then this
-- operation returns only the gateway ARN in the response body. To specify
-- which gateway to describe, use the Amazon Resource Name (ARN) of the
-- gateway in your request.
