Unable to add VMQ Setting via Powershell, if the Adapter Policy with VXLAN Enabled (Win-HPN) is used

[rfiodv]

Describe the bug
If you try to set VMQ settings via Powershell and you use the adapter policy Win-HPN, you get an error message (see below) “Cannot enable VXLAN and VMQ simultaneously on Virtual Ethernet Interface”
The whole behavior only occurs with the Powershell, if you do the whole thing via the Intersight WebUI, this operation works without problems.
What is the problem for us now is that we need this setting to be set automatically and according to the Cisco instructions it is also intended.

To Reproduce
Steps to reproduce the behavior

• PowerShell code snippet (when possible)
  `$vmqsetting = Initialize-IntersightVnicVmqSettings -Enabled $true -NumSubVnics 64 -VmmqAdapterPolicy "MQ"

  $vnic = New-IntersightVnicEthIf -Cdn $Cdn -Name "vNIC0" -MacPool $MACPool -EthAdapterPolicy $EthAdapterPolicyRef -EthQosPolicy $EthQoSRef -FabricEthNetworkControlPolicy $EthNetworkControlPolicyRef -FabricEthNetworkGroupPolicy @($EthNetworkGroupPolicyRef) -Placement $vNICPlacement -LanConnectivityPolicy $LanConnectivityRef -PinGroupName $PinGroupName -VmqSettings $vmqsetting

77 | … $vnic = New-IntersightVnicEthIf -Cdn $Cdn -Name "vNIC0" -M …
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Version used

• Intersight PowerShell Module version? - 1.0.11.17956
• Intersight Appliance Version (if using an Intersight Appliance as target) - Intersight EU SaaS

Expected behavior
Able to Set VMQ Settings while Win-HPN Adapter Policy is used.

The Intersight UI is using the bulk/Requests API resource to configure for VXLAN and VMQ in a single call. Here's an example of what that should look like in PowerShell:
$Organization1 = Get-IntersightOrganizationOrganization -Moid "6418bfd46972652d30a596ef" | Get-IntersightMoMoRef
$mo1 = New-IntersightVnicLanConnectivityPolicy -AzureQosEnabled $false -IqnAllocationType "None" -IqnPool $null -Name "vxlan-vmq" -Organization $Organization1 -PlacementMode "Custom" -StaticIqnName "" -Tags @() -TargetPlatform "FIAttached"
$Body2 = ConvertFrom-Json -InputObject '{"Cdn":{"Source":"vnic"},"EthAdapterPolicy":"64f0b7af325865c901f1f849","EthQosPolicy":"64f0b79c325865c901f1f111","FabricEthNetworkControlPolicy":"64f0b7876f62693001f2be0e","FabricEthNetworkGroupPolicy":["64f0b7706f62693001f2b585"],"FailoverEnabled":false,"LanConnectivityPolicy":"673637544625e5d20111bd06","MacAddressType":"POOL","MacPool":"64f0b7526962753101f2ddc5","Name":"eth-test","Order":0,"Placement":{"AutoPciLink":true,"AutoSlotId":true,"SwitchId":"A"},"VmqSettings":{"Enabled":true,"MultiQueueSupport":true,"NumSubVnics":64,"VmmqAdapterPolicy":"64f0b7af325865c901f1f849"}}'
$Requests12 = Initialize-IntersightBulkRestSubRequest -Body $Body2 -ObjectType "BulkRestSubRequest" -ClassId "BulkRestSubRequest"

$mo2 = New-IntersightBulkRequest -Requests @($Requests12) -Uri "/v1/vnic/EthIfs" -Verb "POST"

The example above was auto generated and the request body isn't correct. I'll work a corrected example and post once it's working.
