Modified files: sys/compat/ndis subr_ndis.c subr_ntoskrnl.c Log: Correct the API for Windows interupt handling a little. The prototype for a Windows ISR is 'BOOLEAN isrfunc(KINTERRUPT *, void *)' meaning the ISR get a pointer to the interrupt object and a context pointer, and returns TRUE if the ISR determines the interrupt was really generated by the associated device, or FALSE if not. I had mistakenly used 'void isrfunc(void *)' instead. It happens the only thing this affects is the internal ndis_intr() ISR in subr_ndis.c, but it should be fixed just in case we ever need to register a real Windows ISR vi IoConnectInterrupt(). For NDIS miniports that provide a MiniportISR() method, the 'is_our_intr' value returned by the method serves as the return value from ndis_isr(), and 'call_isr' is used to decide whether or not to schedule the interrupt handler via DPC. For drivers that only supply MiniportEnableInterrupt() and MiniportDisableInterrupt() methods, call_isr is always TRUE and is_our_intr is always FALSE. In the end, there should be no functional changes, except that now ntoskrnl_intr() can terminate early once it finds the ISR that wants to service the interrupt.
