might try and keep using the old address until their arp table

Maybe this ought to be done for INET6 addresses as well but i have
no idea how to do it. It should be pretty straightforward though.

o Prepend underscores to the ntohl() family to help deal with
complexities associated with having MD (asm and inline) versions, and
having to prevent exposure of these functions in other headers that
happen to make use of endian-specific defines.
o Create weak aliases to the canonical function name to help deal with
third-party software forgetting to include an appropriate header.

the only check is whether a '\0' appears in the buffer. This is useful
when pulling in a structure from userland that may contain one or more

If you want QLogic to look at a potential f/w problem for FC cards, you really
have to provide them info in the format they expect. This involves dumping
a lot of hardware registers (> 300 16 bit registers) and a lot of SRAM
(> 128KB minimum). Thus all of this code is #ifdef protected which will
become an option so that the memory allocation of where to dump the crash
image is pretty expensive. It's worth it if you have a reproducible problem
because they have some tools that can tell them, given the f/w version,
the precise state of everything.

Appologies for making this one bulk commit, but I have tested all these
changes together and don't want to break anything by trying to disentangle
it.
o Make debugging a sysctl/tunable
o Remove flags word from yenta chip info, it is unused
o Make 16-bit card I/O range and 32-bit card I/O range tunables
o Start the rename of pccbb to cbb to match NetBSD by misc renames.
o Kill the now bogus list of softcs to create kthread. Instead, just
create the kthread in the attach routine.
o Remove sc_ from some structure names. It isn't needed.
o Refine chipset lookup code.
o Match generic PCI <-> CardBus bridges. We specifically don't generically
match PCI PCMCIA bridges because they are not, with one exception, yenta
devices.
o Add some comments about the why we need to have a function table ala
OLDCARD
o The PCI interrupt routing by using the ExCA registers is needed for
for all bridges, per the spec, not just TI ones.
o Collapse TOPIC95 and TOPIC95B.
o Using the ToPIC 97 and 100 datasheets, try to support these bridges better,
but more work is needed.
o Generally clarify some XXX comments and add them in a few places where
things didn't look right to me.
o Move interrupt generating register access until after we establish an ISR.
o Add support for YV and XV cards. X and Y are numbers to be determined
later (but maybe never).
o factor powerup code for 16-bit and 32-bit cards.
o When a card supports more than one voltage, prefer the lowest supported
volage. Windows does this, and MS's design guides imply this is the
right thing to do.
o Document race between kthread_exit(0) and kldunload's unmapping of pages
that John Baldwin and I discovered.
o Debounce the CSC interrupt a little better.
o When a 16-bit card is inserted when we don't have a pccard child,
warn about it better. Ditto for 32-bit card.
o Ack ALL the interrupt bits that we get, not just 0x1.
o maybe a couple minor style nits corrected.

the structure definitions come from NetBSD to make it easier to share card
definitions. The driver only acts as a shim between the pci bus and the
sio driver. Later pci parallel ports could also be supported through this
driver. Support for most single and multiport pci serial cards should be
as simple as adding its definition to pucdata.c

In order of importance:
+ each cluster now uses private data structures (filtering and
local address tables) so you can treat them as fully independent
switches. This part of the work was supported by:
Cisco Systems, Inc. - NSITE lab, RTP, NC.
+ cleaned up the handling of configuration, so the system will behave
much better when real or pseudo devices are dynamically attached
or detached. It should also not panic anymore on systems with large
number of devices, closing a few existings PRs on the topic.
+ while at it, add support for VLAN. This means that a FreeBSD box
can now work as a real VLAN switch, with trunk interfaces etc.
As an example:
ifconfig vlan0 vlan 3 vlandev dc0
ifconfig vlan1 vlan 4 vlandev dc0
net.link.ether.bridge_cfg="vlan0:3,dc1:3,vlan1:4,dc1:4"
uses dc0 as a trunk interface, and dc1 and dc3 as ports on vlans 3 and 4
You get the idea...
NOTA BENE: by default bridge_cfg is initialised to "" so even if
you enable bridging, no packets will be bridged until you set the
list of interfaces on which you want this to happen.
+ large restructuring of the code, moving private vars and types from
bridge.h to bridge.c.
+ added a lot of comments to the code to explain how to use it.
This escaped because DEVICE_POLLING is disabled in LINT being

The new pmap.c is based on NetBSD's newer pmap.c (for the mpc6xx processors)
which is 70% faster than the older code that the original pmap.c was based
on. It has also been based on the framework established by jake's initial
sparc64 pmap.c.
There is no change to how far the kernel gets (it makes it to the mountroot

Users who should be running current should know about turning WITNESS
