What ipl should be used when using IF_ENQUEUE or IFQ_ENQUEUE on
ifnet.if_snd queues? The 4.4BSD book says splimp() and the comments
in /sys/net/if.h say splimp(). Since splimp() has been removed
I'm guessing splsoftnet() or splnet() are required. Which is it?

What's the difference between splsoftnet() and splnet()?

Why was splimp() used before?
