sorry, my English is so poor, i have saw the port stats. from the reply, we can know the number of transmitted/received packets(bytes) and the number of packets dropped by RX(TX). if i want to know the buffer size of the packets in the port, (rx_bytes- tx_bytes) is right? or (rx_packets - tx_packets - tx_dropped - rx_dropped) is right? can you tell me the relationship between rx_packets, tx_packets, rx_dropped and tx_dropped? Thank you very much !!!
