Hi, The i40e driver of network card 710 experiences severe packet loss. The main reason is the increase in rx_rropped statistics in ethtool-S. By examining the i40e driver source code, it was found that rx_rropped is the statistical representation of rx_iscaffolds. This value is written in the register of the network card. Under what circumstances will this rx-discaffolds increase? At present, after adjusting the ringbuffer size of the network card to the maximum 4096, the customer environment still loses packets. The improvement effect is not significant. May I ask if there are any other optimization plans? For example: ethtool -S ens2f0 NIC statistics: rx_packets: 18198913247 tx_packets: 13051235581 rx_bytes: 10555544090204 tx_bytes: 2367746549153 rx_errors: 0 tx_errors: 0 rx_dropped: 92572379 tx_dropped: 0 Please let me know. Thanks. Regards, CC97
