what is going on that the current:

proc1: close
devsw->close( R/O, proc1 )

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.

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.
"the device doesn't support a dump routine"
Only print "dump succeeded" when 0 is returned, instead of when an unexpected
error number is returned, print that error number.

While I was in the neighborhood, I noticed that I was still using
#define NFPX 1 in all of the Makefiles that I'd copied from the fxp
module. I don't really use #define Nfoo X so it didn't matter, but
I decided to customize this correctly anyway.

as PCI->HOST bridges on my (440BX) box.
My change is to remove the test at the beginning entirely, letting the
switch on the device ID happen first. If the device ID is unknown, then
(in the default case) check for the generic PCIS_BRIDGE_HOST tag. This
should allow wierd cases (eg: wpaul's IMS VL bridge) to work by using the
id override. This strategy is more in line with the other PCI match
methods we use elsewhere,
I only have a limited testbed, but having my USB etc devices detected as
PCI->HOST bridges doesn't look good.
