- * The internet code runs off software interrupts.
- * There is one software interrupt level for each IP layer protocol
- * (e.g. IP, PUP, etc), and each such interrupt traps to the lowest
- * level routine for that protocol.
- *
- * You can switch into the network by doing splnet() 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).  Splimp is an ipl high enough to block all imps.
- * While manipulating the mbuf buffer pool you have to block imps.
