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