driver certification

Does anybody know whether there is certification tests for network driver?
I.e. some procedure that will say: "yes, this driver do what proper network 
driver should do" or "no, you don't comply with items a,b,c..."

If in kernel it is not defined yet, anyone from distributors (RedHat, SUSE) or 
vendors (HP,IBM), do you have one?

If it is not exist yet, how could I set criteria for validation of the driver?
