* The networking code runs off software interrupts. |
* |
* You can switch into the network by doing splsoftnet() 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 |
* at timeout time). |
* |
* The routine to request a network software interrupt, setsoftnet(), |
* is defined in the machine-specific include files. |

* 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. |
