[dpdk-dev] [PATCH v2 1/4] virtio-user: use virtual address in cq

[Jianfeng Tan <jianfeng.tan@intel.com>]

Change to use virtio_net_hdr_mem instead of physical addr of memzone
when sending contrl queue commands. The virtio_net_hdr_mem has been
initialized to use virtual address under the case of virtio-user.
