NVMeTCP offload devices might have different limitations of the allowed options, for example, a device that does not support all the queue types. With tcp and rdma, only the nvme-tcp and nvme-rdma layers handle those attributes and the HW devices do not create any limitations for the allowed options. An alternative design could be to add separate fields in nvme_tcp_ofld_ops such as max_hw_sectors and max_segments that we already have in this series.
