Hello,

Does bdev_nvme_attach_controller give the option to have tcp with zcopy
enabled (initiator side)?

       "config": [
        {
            "method": "bdev_nvme_attach_controller",
            "params": {
            "trtype": "TCP",
            "adrfam": "IPv4",
            "name": "Nvme0",
            "subnqn": "nqn.2016-06.io.spdk:cnode1",
            "traddr": "1.1.0.2",
            "trsvcid": "4420"
            }
         },
