The mode by which this port will be Rate-Limited
on ingress. If rateLimitPerPortOnly is configured,
there will be a single maximum rate for the entire
port. If rateLimitPerQueue is configured, the values
for each of the four queues indicate the maximum
percentage of port traffic that may be received by
that queue (the sum of these values must not exceed
100). When rate-limiting is disabled, there are no
maximum controls on ingress for this port.
