Network offloads compatibility configure to null

Describe the bug

Hi, I am trying to create DVS and when I connect to the Vcenter the Network offloads compatibility always sets to null and brings this

"This distributed switch is configured for network offloads with null compatibility.
Incompatible settings are disabled or not available."

Reproduction steps

    spec = vim.DistributedVirtualSwitch.CreateSpec()
    spec.configSpec = vim.DistributedVirtualSwitch.ConfigSpec()
    spec.configSpec.name = name

    # Define uplink ports
    spec.configSpec.uplinkPortPolicy = vim.DistributedVirtualSwitch.NameArrayUplinkPortPolicy()
    spec.configSpec.uplinkPortPolicy.uplinkPortName = ['uplink1', 'uplink2']

    # Set the product version
    spec.productInfo = vim.dvs.ProductSpec()
    spec.productInfo.version = config.dvs_ver

    # Configure uplink teaming policy
    teaming_policy = vim.dvs.VmwareDistributedVirtualSwitch.UplinkPortOrderPolicy()
    teaming_policy.activeUplinkPort = ['uplink1']
    teaming_policy.standbyUplinkPort = ['uplink2']

    uplink_teaming_policy = vim.dvs.VmwareDistributedVirtualSwitch.UplinkPortTeamingPolicy()
    uplink_teaming_policy.uplinkPortOrder = teaming_policy

    port_config = vim.dvs.VmwareDistributedVirtualSwitch.VmwarePortConfigPolicy()
    port_config.uplinkTeamingPolicy = uplink_teaming_policy

    spec.configSpec.defaultPortConfig = port_config

    # Set Network offloads compatibility to None
    spec.capability = None

    # Get datacenter and create DVS
    datacenter = get_obj_or_raise_exc(si.content, [vim.Datacenter], config.datacenter_name)

    if is_real_run():
        task = datacenter.networkFolder.CreateDVS_Task(spec)
        WaitForTask(task, si=si)
        dvs = task.info.result
    else:
        dvs = None

    return dvs

Expected behavior

Network offloads compatibility sets to Null

Additional context

No response

Start with the reproduction in the issue and inspect how vim.DistributedVirtualSwitch.CreateSpec, spec.capability, and datacenter.networkFolder.CreateDVS_Task represent network offloads compatibility. Reproduce the DVS creation against vCenter, then compare the resulting compatibility value and warning with the stated expected behavior; the issue needs clarification because both observed and expected behavior describe null.
