* The networking code runs off software interrupts.
* You can switch into the network by doing splnet() and return by splx().
* The software interrupt level for the network is higher than the software
* level for the clock (so you can enter the network in routines called
#define setsoftnet() mtpr(SIRR, 12)
* Each ``pup-level-1'' input queue has a bit in a ``netisr'' status
* word which is used to de-multiplex a single software
* interrupt used for scheduling the network code to calls
* on the lowest level routine of each protocol.
