> Subject: [dpdk-dev] [PATCH v2] vhost: fix zero-copy cannot be enabled
>
> This patch fixes the situation where vhost-user cannot start as server with
> dequeue_zero_copy enabled.
>
> Using flag instead of vsocket->is_server to determine whether vhost-user is in
> client mode. Because vsocket->is_server is not ready at this time.
