VMQ and VMMQ Default Accelerations
Table 16-2 lists the VMQ and VMMQ default and other values for accelerations in 
Windows Server 2019 for Dell 41xxx Series Adapters.
Single VPort Pool
The 41xxx Series Adapter supports the Single VPort Pool parameter, which 
allows the system administrator to assign any available IOVQueuePair to either 
Default-VPort, PF Non-Default VPort, or VF Non-Default VPort. To assign the 
value, issue the following Windows PowerShell commands:
 Default-VPort:
Set-VMSwitch -Name <vswitch name> -DefaultQueueVmmqEnabled:1 
-DefaultQueueVmmqQueuePairs:<number>

quantity of queue pairs for the Default-VPort, because it may impact system 
performance.
