Select the maximum packet size that can be received by this physical port.
Valid values are 1500 non-jumbo frame (1500 bytes per frame) or 9000 jumbo frame (9000 bytes per frame). The 9000 jumbo frame setting applies only when the transfer speed is 1000 Mbps or 10 Gbps. If the physical port uses another transfer speed, the maximum packet size is always 1500 bytes per frame.
