When enabling the .net.userLevelNetworking, the automatic approach does not work with Mellanox interfaces.

Actual Result:
Thess interfaces requires additional configuration for reducing the vectors.

1. mstconfig -y -d <device bus address> set NUM_PF_MSIX=<number of channels>

However, when there are hundreds of nodes, it is difficult to run above command manually.

Expect Result:
The additional configuration for reducing the vectors can be done automatically.
