  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(),
