The Disable-NetAdapterSriov cmdlet disables Single-Root I/O Virtualization (SR-IOV) on the network adapter. SR-IOV enables network traffic to
bypass the software switch layer of the Hyper-V virtualization stack. As a result, the I/O overhead in the software emulation layer is reduced
and can achieve network performance that is nearly the same performance as in non-virtualized environments.
This cmdlet prevents the adapter from using SR-IOV until enabled again. While SR-IOV is disabled, Windows Server® 2012 and later will not
attempt to allocate a virtual function (VF) to a virtual machine (VM). If VFs from this network adapter are allocated to any VM, then the VFs
are revoked and each VM interface reverted to the synthetic network path.

EXAMPLE 1
PS C:\> Disable-NetAdapterSriov -Name "Ethernet 1"
This example disables SR-IOV on the network adapter named Ethernet 1 and restarts the network adapter.
EXAMPLE 2
PS C:\>$netAdapter3 = Get-NetAdapter –Name "Ethernet 3"
PS C:\>Disable-NetAdapterSriov –InputObject $netAdapter3
A version of the cmdlet that uses the pipeline to select the network adapter named Ethernet 3 and pipes that object into this cmdlet.
PS C:\> Get-NetAdapter –Name "Ethernet 3" | Disable-NetAdapterSriov
This example gets a network adapter named Ethernet 3, and disables the network adapter before restarting the network adapter.
EXAMPLE 3
PS C:\> Disable-NetAdapterSriov -Name "Ethernet 2" -NoRestart
This example disables SR-IOV on the network adapter named Ethernet 1 without restarting the network adapter.
