Notes:

1. It is enough to just disable flow control in NIC properties but depending on the requirement, you can disable other options as mentioned above.

2. Most of the modifications of network card properties are under the circumstance of diskless. If you can't modify the information in a diskless situation, please try to modify with disks being attached. Besides, if you failed to disable flow control on the client side even with Super Client on Device Manager, we recommend modifying before uploading the image. If you have multiple specs, you need to modify every network adapter before uploading the image. If the network adapter type is the same, just need to disable the flow control once.
