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.

Only print "dump succeeded" when 0 is returned, instead of when an unexpected

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.

correctly. It has the following code:
if (class != PCIC_BRIDGE || subclass != PCIS_BRIDGE_HOST)
return NULL;
My 486 has an Integrated Micro Solutions PCI bridge which identifies
itself as subclass PCIS_BRIDGE_OTHER, not PCIS_BRIDGE_HOST. Consequently,
it gets ignored. In my opinion, the correct test should be:
if ((class != PCIC_BRIDGE) && (subclass != PCIS_BRIDGE_HOST))
return NULL;
That way the test still succeeds because the chip's class is PCIC_BRIDGE.
Clearly it's not reasonable to expect all host to PCI bridges to always
have a subclass of PCIS_BRIDGE_HOST since I've got one that doesn't.
This way the sanity test should remain relatively sane while still allowing
some oddball yet correct hardware to work. If somebody has a better way
to do it, go ahead and tweak the test, but be aware that
class == PCIC_BRIDGE and subclass == PCIS_BRIDGE_OTHER is a valid case.
While I was here, I also added an explicit ID string for the IMS chipset.
I also dealt with a minor style nit: it's bad karma not to have a default
case for your switch statements, but the one in this routine doesn't have
one. The default string of "Host to PCI bridge" is now assigned in a
default case of the switch statement instead of initializing "s" with the
string before the switch and then not having any default case.
