gld_intr() Function

uint_t gld_intr(caddr_t);

gld_intr() is GLD's main interrupt handler. Normally, gld_intr() is specified as the interrupt routine in the device driver's call to ddi_add_intr(9F). The argument to the interrupt handler (specified as int_handler_arg in the call to ddi_add_intr(9F)) must be a pointer to the gld_mac_info(9S) structure. gld_intr() will, when appropriate, call the device driver's gldm_intr() function, passing that pointer to the gld_mac_info(9S) structure. However, if the driver uses a high-level interrupt, it must provide its own high-level interrupt handler and trigger a soft interrupt from within that. In this case, gld_intr() would normally be specified as the soft interrupt handler in the call to ddi_add_softintr(). gld_intr() will return a value appropriate for an interrupt handler.
