Verify RoCE in Windows

Language:

Create a file share on the remote system and open that share.
Open that share with Windows Explorer or the net use command. To avoid a speed bottleneck when the hard disk is reading or writing, use a RAM disk as the network share.
Run these commands from the PowerShell.
```
Get-SmbMultichannelConnection | fl *RDMA*
ClientRdmaCapable : True
ServerRdmaCapable : True
```
If both Client and Server are True, any file transfers over this SMB connection use SMB.
Enable or disable SMB Multichannel support.
On the Server side:
```
Enable: Set-SmbServerConfiguration -EnableMultiChannel $true
Disable: Set-SmbServerConfiguration -EnableMultiChannel $false
```
On the Client side:
```
Enable: Set-SmbClientConfiguration -EnableMultiChannel $true
Disable: Set-SmbClientConfiguration -EnableMultiChannel $false
```
Note - By default, the driver sets up two RDMA connections for each network share per IP address (on a unique subnet). You can increase the number of RDMA connections by adding multiple IP addresses, each with different a subnet, for the same physical port under test. Multiple network shares can be created and mapped to each link partner using the unique IP addresses that you created.
