card bus bridges.
We now always use pci interrupts for pci cards. This will allow us to
more easily configure things. You must change your IRQ lines in
/etc/pccard.conf to match what we've probed. I'm not sure the right
way to deal with this right now.
Development of pci pcmcia has been funded by Monzoon Networks AG. I
am grateful for their generosity.

for card change interrupts is different than the pci stuff that's
coming soon. Set the management irq in different ways. If
pci_parallel interrutp routing, then use the PCI way of getting
interrupts. Move polling mode into pcic_isa since when we're routing
via pci polling doesn't work because many bridges (systems hang solid).
If we're routing interrupts via pci, they can be shared, so flag them
as such.
Note, this doesn't actually change anything since the pci attachment
isn't quite ready to be committed.
A attacker sending a lot of bogus fragmented packets to the target
(with different IPv4 identification field - ip_id), may be able
to put the target machine into mbuf starvation state.
By setting a upper limit on the number of reassembly queues we
prevent this situation.
This upper limit is controlled by the new sysctl
net.inet.ip.maxfragpackets which defaults to 200,
as the IPv6 case, this should be sufficient for most
systmes, but you might want to increase it if you have
lots of TCP sessions.
I'm working on making the default value dependent on
nmbclusters.
If you want old behaviour (no upper limit) set this sysctl
to a negative value.
If you don't want to accept any fragments (not recommended)
set the sysctl to 0 (zero).

Second, set the IFF_RUNNING flag on an interface after its

The 3C509-TX card apparently had a slightly different version of the
chip, and has problems when this register is set. The problem does
not appear on the 3C509{BC} cards, but since only the fxp driver needs
specific bits set, conditionalize on that.
canonical: define a versioned struct xswdev, and add a sysctl node
handler that allows the user to get this structure for a certain device
index by specifying this index as last element of the MIB.
This new node handler, vm.swap_info, replaces the old vm.nswapdev
and vm.swapdevX.* (where X was the index) sysctls.

correct. Also noted that while a checksum field is defined for the

the interface conversion to platform.pci_intr_route(). I've left the
platform.pci_intr_route() function pointer in place, as well as
alpha_pci_route_interrupt(), but no platform currently implements it.
To work around the removal of alpha_platform_assign_pciintr(cfg);
from the pci probe code, I've hooked in calls to platform.pci_intr_map()
in pcib_read_config (similar to the x86 APIC_IO ifdef in pci_cfgregread)
for every chipset that has a platform which needs it.
While here, I've removed the interupt mapping/routing code from the
AS2x00 platform because its not required (it has never been present in
-stable).

Only tun0 -> tun32767 may now be opened as struct ifnet's if_unit
is a short.
It's now possible to open /dev/tun and get a handle back for an available
tun device (use devname to find out what you got).
The implementation uses rman by popular demand (and against my judgement)
to track opened devices and uses the new dev_depends() to ensure that
all make_dev()d devices go away before the module is unloaded.

- move the sysctl code to kern_intr.c
- do not use INTRCNT_COUNT, but rather eintrcnt - intrcnt to determine
the length of the intrcnt array
- move the declarations of intrnames, eintrnames, intrcnt and eintrcnt
from machine-dependent include files to sys/interrupt.h
- remove the hw.nintr sysctl, it is not needed.
- fix various style bugs
