4 | * The networking code runs off software interrupts. | |
5 | * | |
6 | * You can switch into the network by doing splnet() and return by splx(). | |
7 | * The software interrupt level for the network is higher than the software | |
8 | * level for the clock (so you can enter the network in routines called | |
9 | * at timeout time). | |
