Hi!

I'm working on an IP encapsulation protocol, a la IPSec. Since I need to
manage sessions, I have "shared datum" among several IP packets, so I need
to splnet() / splx() the code. A simple way to do it is just to protect my
whole code inside a splnet(), and then splx() when it exits.
I that a bad idea? Should I only protect some portions, and why?

Thanks
