Why does Hyper-V not enable this VMSwitchExtension?

The long and short of it is:

PS C:\WINDOWS\system32> Get-VMSwitch vSwitch

Name    SwitchType NetAdapterInterfaceDescription
----    ---------- ------------------------------
vSwitch External   Intel(R) Ethernet Connection (2) I219-V

  False

In other words, I can't enable this VMSwitchExtension, or it continually disables itself. This also happens in the Hyper-V management UI for the virtual switch (I set the checkbox, hit ok or apply, close the dialog, reopen the dialog, and the checkbox is unset).

I am relatively unfamiliar with both Hyper-V and Powershell, so any guidance would be appreciated.
