/*

 * 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.
