• rtems/rtems_glue.c: A small patch to the network daemon task code. I just added code to check the return value of the rtems_bsdnet_event_receive function. Only when this function returns a SUCCESSFUL status, will the event flags be checked. This is more of a code cleanup issue than a bug. The patch will just ensure the ipintr() and arpintr() functions are only called when a event is signaled.
