System checkstops if RxFIFO overruns with more requests than the
maximum possible number of CRBs allowed in FIFO at any time. So
max credits value (rxattr.wcreds_max) is set and is passed to
vas_rx_win_open() by the the driver.

This seems like it should be a bug fix or merged in the NX fault
window register patch or something.

Yes, it is a bug fix and can affect with any VAS windows, Not related to
NX fault window. Hence added as separate patch. 
 

Thanks,
