Currently, for an app to open a raw QP from user space, we (verbs)

Suppose we allow to user to provide source mac+vlan when creating the 
QP or when modifying its state, and the HW can enforce that -- in that 
case I think its OK to remove that restriction e.g ala what is allowed 
today with user space UD QPs when the fabric is IB.

Or.

We have similar requirements from customers.   I don't understand how 
mac+vlan allows the driver to enforce anything?  Can you explain this 
further?
