Don't assume that a 500 microsecond time limit should be used for all receive endpoints that support aggregation. Instead, specify the time limit to use in the configuration data. Set a 500 microsecond limit for all existing RX endpoints, as before. Checking for overflow for the time limit field is a bit complicated. Rather than duplicate a lot of code in ipa_endpoint_data_valid_one(), call WARN() if any value is found to be too large when encoding it.
