Hi, all:
I tried to test the effort of nic queue's ring-size, but nic' tx vring-size is always 256. finally i found the code. could you tell why ? thanks ----- n->net_conf.tx_queue_size = MIN(virtio_net_max_tx_queue_size(n), n->net_conf.tx_queue_size); n->net_conf.tx_queue_size is 256 if peer->info->type != NET_CLIENT_DRIVER_VHOST_USER.
