Step 1. Enable Data Center Bridging (DCB).
 To configure QoS on the host:
Step 1. Change the Windows PowerShell execution policy.
Step 2. Remove the entire previous QoS configuration.
Step 3. Set the DCBX Willing parameter to false as Mellanox drivers do not support this feature.
Step 4. Create a Quality of Service (QoS) policy and tag each type of traffic with the relevant priority.
In this example, TCP/UDP priority 1, ND/NDK priority 3 is used.
Step 5. [Optional] If VLANs are used, mark the egress traffic with the relevant VlanID.
The NIC is referred as "Ethernet 4” in the examples below.
Step 6. [Optional] Configure the IP address for the NIC.
If DHCP is used, the IP address will be assigned automatically.
Step 7. [Optional] Set the DNS server (assuming its IP address is 192.168.1.2).
Step 8. Disable Priority Flow Control (PFC) for all other priorities except for 3.
