46 * The networking code runs off software interrupts.
48 * You can switch into the network by doing splsoftnet() and return by splx().
49 * The software interrupt level for the network is higher than the software
50 * level for the clock (so you can enter the network in routines called
53 * The routine to request a network software interrupt, setsoftnet(),
54 * is defined in the machine-specific include files.
58 * Each ``pup-level-1'' input queue has a bit in a ``netisr'' status
59 * word which is used to de-multiplex a single software
60 * interrupt used for scheduling the network code to calls
61 * on the lowest level routine of each protocol.
