PCIe: Which devices supports more then one Virtual Channel (VC)?

Thanks Nathan!

What I don't get is, why then, in all the documentations for the Avalon Interface the 7 VCs are mentioned?

They always describe the "Address Map of Hard IP Configuration Space Registers", where VC0-VC7 is mentioned. Is there any way to access to this configuration space registers?

E.g. for the V-Series:

Another question: Which Intel FPGAs/SoCs supports more than one TC (Traffic Class)?

Thanks in advance!
