Summary:                    [patch] Support for generic HFC-4S cards
Description: 
A patch to add some basic support of other HFC-4S -based PCI cards (such as
the ones made by Junghanns). 

Status: gets rid of the echo canceller messages when not needed, but still
needs work.

Specifically:
* It adds too broad a range of cards (which also include bero.net cards) 
* The range may include some 2-ports cards, which will probably not work.

Not yet tested to work, though it it is at least configured.

---------------------------------------------------------------------- 
First day using dahdi impression: fantastic!
Post Delay Dial is dramatically lower (almost istantaneous, while using
mISDN I had to wait several seconds, let's say more than 5 and near 10)

Also taking calls using *8 is again possible, while using latest mISDN
/*1.4.23 wasn't
---
I would like to have a patch in order to support also single BRI HFC
cards, so I tried to menage it by myself.. with no luck!
I started modifing
dahdi-tools-2.1.0.2/xpp/perl_modules/Dahdi/Hardware/PCI.pm adding
        '1397:2bd0/1397:2bd0'   => { DRIVER => 'wcb4xxp', DESCRIPTION =>
'HFC-1S ISDN BRI card' },
(and removing the corresponding line about 1397:2bd0)

then I added 
        HFC1S,          /* HFC-1S Generic  single BRI PCI       */
to the enumeration into
dahdi-linux-2.1.0.4/drivers/dahdi/wcb4xxp/wcb4xxp.h

and also modified dahdi-linux-2.1.0.4/drivers/dahdi/wcb4xxp/base.c 
according to what I see you did in the patch, i.e. I added:

static struct devtype hfc1s =   { "Generic HFC Chipset single BRI PCI",
.ports = 1, .has_ec = 0, .card_type = HFC1S };

and aother...
The problem I have is that recompiling dahdi_hardware now reports:

pci:0000:05:00.0     wcb4xxp+     1397:2bd0 HFC-S ISDN BRI card

lspci -nn -v reports:

05:00.0 Network controller [0280]: Cologne Chip Designs GmbH ISDN network

        Kernel driver in use: wcb4xxp

but dmesg, on loading wcb4xxp drivers, says:
dahdi: Telephony Interface Registered on major 196

wcb4xxp 0000:05:00.0: Unknown/unsupported controller detected (R_CHIP_ID =
0xff)
ACPI: PCI interrupt for device 0000:05:00.0 disabled

The question is: do you think it would be nice to go on on this road and
try to support also this kind of boards ? Do you want me to try to modify
something or uploading this patch (I should have a License, having uploaded
a patch last summer...). Is it better to start another bug ?
