vmq and vrss Intel Ethernet Server Adapter X520-2

We have several servers with Intel Ethernet Server Adapter X520-2, each server has two cards.

 

In the documentation says that vmq an vrss are compatible

 

We do not know why depending on whether you enable the vrss is 31 vmq or 63 with the vrss disabled?
