To: netdev
Remove wanrouter as it's obsolete and has not been updated
by sangoma since 2.4.3 or so and it's not used anymore.
Remove obsolete cyclomx drivers.
Update files that include now deleted wanrouter bits.

Resending in a different form because
git format-patch -M -D creates a patch
that can not be applied cleanly via git am.

-* 1999/11/11 acme set_current_state(TASK_INTERRUPTIBLE), code
-* cleanup
-* 1999/11/08 acme init_cyc2x deleted, doing nothing
-* 1999/11/06 acme back to read[bw], write[bw] and memcpy_to and
-* fromio to use dpmbase ioremaped
-* 1999/10/26 acme use isa_read[bw], isa_write[bw] & isa_memcpy_to
-* & fromio
-* 1999/10/23 acme cleanup to only supports cyclom2x: all the other
-* boards are no longer manufactured by cyclades,
-* if someone wants to support them... be my guest!
-* 1999/05/28 acme cycx_intack & cycx_intde gone for good
-* 1999/05/18 acme lots of unlogged work, submitting to Linus...
-* 1999/01/03 acme more judicious use of data types
-* 1999/01/03 acme judicious use of data types :>
-* cycx_inten trying to reset pending interrupts
-* from cyclom 2x - I think this isn't the way to
-* go, but for now...
-* 1999/01/02 acme cycx_intack ok, I think there's nothing to do
-* to ack an int in cycx_drv.c, only handle it in
-* cyx_isr (or in the other protocols: cyp_isr,
-* cyf_isr, when they get implemented.
-* Dec 31, 1998 acme cycx_data_boot & cycx_code_boot fixed, crossing
-* fingers to see x25_configure in cycx_x25.c
-* work... :)
-* Dec 26, 1998 acme load implementation fixed, seems to work! :)
-* cycx_2x_dpmbase_options with all the possible
-* DPM addresses (20).
-* cycx_intr implemented (test this!)
-* general code cleanup
-* Dec 8, 1998 Ivan Passos Cyclom-2X firmware load implementation.
-* Aug 8, 1998 acme Initial version.

-* ============================================================================
-* 2001/01/12 acme use dev_kfree_skb_irq on interrupt context
-* 2000/04/02 acme dprintk, cycx_debug
-* fixed the bug introduced in get_dev_by_lcn and
-* get_dev_by_dte_addr by the anonymous hacker
-* that converted this driver to softnet
-* 2000/01/08 acme cleanup
-* 1999/10/27 acme use ARPHRD_HWX25 so that the X.25 stack know
-* that we have a X.25 stack implemented in
-* firmware onboard
-* 1999/10/18 acme support for X.25 sockets in if_send,
-* beware: socket(AF_X25...) IS WORK IN PROGRESS,
-* TCP/IP over X.25 via wanrouter not affected,
-* working.
-* 1999/10/09 acme chan_disc renamed to chan_disconnect,
-* began adding support for X.25 sockets:
-* conf->protocol in new_if
-* 1999/10/05 acme fixed return E... to return -E...
-* 1999/08/10 acme serialized access to the card thru a spinlock
-* in x25_exec
-* 1999/08/09 acme removed per channel spinlocks
-* removed references to enable_tx_int
-* 1999/05/28 acme fixed nibble_to_byte, ackvc now properly treated
-* if_send simplified
-* 1999/05/25 acme fixed t1, t2, t21 & t23 configuration
-* use spinlocks instead of cli/sti in some points
-* 1999/05/24 acme finished the x25_get_stat function
-* 1999/05/23 acme dev->type = ARPHRD_X25 (tcpdump only works,
-* AFAIT, with ARPHRD_ETHER). This seems to be
-* needed to use socket(AF_X25)...
-* Now the config file must specify a peer media
-* address for svc channels over a crossover cable.
-* Removed hold_timeout from x25_channel_t,
-* not used.
-* A little enhancement in the DEBUG processing
-* 1999/05/22 acme go to DISCONNECTED in disconnect_confirm_intr,
-* instead of chan_disc.
-* 1999/05/16 marcelo fixed timer initialization in SVCs
-* 1999/01/05 acme x25_configure now get (most of) all
-* parameters...
-* 1999/01/05 acme pktlen now (correctly) uses log2 (value
-* configured)
-* 1999/01/03 acme judicious use of data types (u8, u16, u32, etc)
-* 1999/01/03 acme cyx_isr: reset dpmbase to acknowledge
-* indication (interrupt from cyclom 2x)
-* 1999/01/02 acme cyx_isr: first hackings...
-* 1999/01/0203 acme when initializing an array don't give less
-* elements than declared...
-* example: char send_cmd[6] = "?\xFF\x10";
-* you'll gonna lose a couple hours, 'cause your
-* brain won't admit that there's an error in the
-* above declaration... the side effect is that
-* memset is put into the unresolved symbols
-* instead of using the inline memset functions...
-* 1999/01/02 acme began chan_connect, chan_send, x25_send
-* 1998/12/31 acme x25_configure
-* this code can be compiled as non module
-* 1998/12/27 acme code cleanup
-* IPX code wiped out! let's decrease code
-* complexity for now, remember: I'm learning! :)
-* bps_to_speed_code OK
-* 1998/12/26 acme Minimal debug code cleanup
-* 1998/08/08 acme Initial version.

-config WAN_ROUTER
- tristate "WAN router (DEPRECATED)"
- depends on EXPERIMENTAL
- ---help---
- Wide Area Networks (WANs), such as X.25, frame relay and leased
- lines, are used to interconnect Local Area Networks (LANs) over vast
- distances with data transfer rates significantly higher than those
- achievable with commonly used asynchronous modem connections.
- Usually, a quite expensive external device called a `WAN router' is
- needed to connect to a WAN.
-
- As an alternative, WAN routing can be built into the Linux kernel.
- With relatively inexpensive WAN interface cards available on the
- market, a perfectly usable router can be built for less than half
- the price of an external router. If you have one of those cards and
- wish to use your Linux box as a WAN router, say Y here and also to
- the WAN driver for your card, below. You will then need the
- wan-tools package which is available from <ftp://ftp.sangoma.com/>.
-
- To compile WAN routing support as a module, choose M here: the
- module will be called wanrouter.
-
- If unsure, say N.

Paul, you can't have HTML content to the list and one of your MIME
sections was HTML, so it was rejected by vger's filters.
Please repost with the HTML stuff removed.
Thanks.

Ah crap. I'd replied via gmail ; today and occasionally in the past as
a convenient short cut when not reading netdev with a "normal" MUA. And
this is not the 1st time gmail has randomly decided to be "helpful" by
mangling plain text like this. Well, I'll be having no more of that BS.
Sorry about that; I know you don't need the extra stupidity to deal
with, esp. at this point in time. Original plain text follows, courtesy
of reliable 1990's MUA technology -- the pull details remain unchanged.
Paul.

I'd hate to see a garbage collection miss out from integration due to
wider testing, so I've taken Joe's commit, put it on today's net-next
and made the following changes:
-keep magic number references but mark them obsolete (nobody asked for
this, but it made sense to me).
-keep the wanrouter.h (uapi and kernel-centric one) files, but with
only the X.25 bits that caused build failures. I have trimmed the enum
to just the bits that were used. Obvious build failures like davem
reported aside, I was concerned that userspace might reference the
headers (got caught on this for my token-ring deletion). I did not find
any userspace uses, but it was packaged with most distro's libc header
content, so who knows? As I did run into this with the token ring
delete, so this is the safer route here -- i.e. leaving a skeleton
header.
I don't want to spam everyone with another giant patch, so note that a
diff from Joe's original and my amendment is shown below (warning - cut
and paste damaged ; not that anyone sane should, but don't try and apply
this delta; it is for review purposes only -- and all lines with "+" are
just restoration of what lines were already there).
For the folks well adapted to git already, I've pushed an equivalent
branch that I have done the build testing of an x86_64 allyesconfig and
allmodconfig, and they compile OK. This is based on the net-next of
today:
The following changes since commit bf0098f22ca7b59e8844ac6882bbae230d34b98d:

I was curious to better figure out what triggered this, now that it
isn't 1AM. It seems the original wasn't plain text, and that gmail
didn't know what else to do with the content from your message when it
arrived as base64 encoded. It looks like it arrived that way to the
list archivers too, and they failed to do anything sensible with their
copy of your message as well.

I only wonder which component is at fault here, the producer side (it
gives the following headers),
Content-Type: Text/Plain; charset=iso-8859-7
Content-Transfer-Encoding: base64
(and the _absence_ of any MIME chunkwrapping)
or the receiver side. (Al)Pine and derivates displays the message
fine, marc.info does not, and gmail presents the body after literally
taking a stab at it.
