38 * The networking code runs off software interrupts.
39 *
40 * You can switch into the network by doing splsoftnet() and return by splx().
41 * The software interrupt level for the network is higher than the software
42 * level for the clock (so you can enter the network in routines called
43 * at timeout time).
44 *
45 * The routine to request a network software interrupt, setsoftnet(),
46 * is defined in the machine-specific include files.
