No one's objected, so I've made this change.  This sort of fixes docs/12220,
by removing the reference to the undocumented getkerninfo(2) call.  So I'll
close the PR as well.

1aefb1d957 Make the default page coloring parameters match a (non-Xeon) Pentium II/III.
This setting is also acceptable for Celerons and Pentium Pros
with less than 1MB L2 caches.

Note: PQ_L2_SIZE is a misnomer.  The correct number of colors is
a function of the cache's degree of associativity as well as its size.

f0706ad422 Userland and manual page changes for probabilistic rule match.
Because the kernel change was done in a backward-compatible way,
you don't need to recompile ipfw if you don't want to use the new
feature.

772759420f Implement probabilistic rule match in ipfw. Each rule can be associated
with a match probability to achieve non-deterministic behaviour of
the firewall. This can be extremely useful for testing purposes
such as simulating random packet drop without having to use dummynet
(which already does the same thing), and simulating multipath effects
and the associated out-of-order delivery (this time in conjunction
with dummynet).

The overhead on normal rules is just one comparison with 0.

Since it would have been trivial to implement this by just adding
a field to the ip_fw structure, I decided to do it in a
backward-compatible way (i.e. struct ip_fw is unchanged, and as a
consequence you don't need to recompile ipfw if you don't want to
use this feature), since this was also useful for -STABLE.

When, at some point, someone decides to change struct ip_fw, please
add a length field and a version number at the beginning, so userland
apps can keep working even if they are out of sync with the kernel.

2336ecd56f Support 21-bit minor numbers. Avoid wasting a byte in their octal
representation by generating the same format as tar-1.13 (use a single
space as the terminator for 7-digit octal numbers).  This is POSIX.1
conformant (2-byte terminators are just a bug or historical wart in
old versions of gnu tar).  All devices created by `MAKEDEV all' except
rsa0.ctl can now be handled by tar(1).
