J1939 at 500kbps

Hi, I am seeing more and more components that run J1939 at 500kbps. I know the specification says it is fixed at 250, but some engine controllers and some hybrid components are now requiring 500kbps. In IQAN design this particular CANbus type has a fixed baud rate, you cannot change it. For now I have to hardcode 29bits messages and use geneic CAN busses to talk to these components, but without all the added benefits of using your "real" J1939 implementation.

Please add selectable baud rate for J1939 busses as well.

Thanks for your great product.
