I know this is normal because dpdk is running in poll mode. However when I set the rx-mode to 'interrupt', it doesn't make any difference. The command line I use looks like: # set interface rx-mode [ifname] interrupt Did I miss anything? Thanks for your attention and any suggestions are welcome. Regards, Xiaodong
