Only because I did not have the time or stomach then to introduce
`struct packet' everywhere. All of the queueing and metadata crap
should be pulled out of mbufs and put into a higher-level object.
It's OK if the higher-level object HAS_A(mbuf), but not IS_A(mbuf).
This is A Lot Of Work, but would seriously clean up the code in a
number of areas.
As a general rule, though, reentrancy was not a particular concern of
the original design -- that's why there are queues and soft ISRs all
over the place -- because you would blow the kernel stack long before
that became an issue.
