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.

@heruan:
Does your card work with other ISDN drivers (e.g. mISDN or CAPI)?

Maybe it is hardware problem and not connected to the DAHDI driver:

Check the PCI latencies of your other(!) PCI cards. They must not block
your PCI bus for too long, else the HFC chip gets stucked:
'lspci -vv' shows the latencies. It should not be above 32 for any card.

In order to reduce the latencies, there should be an option in the BIOS
"PCI latency timer". Nevertheless there are some buggy BIOS, which do not
set the latency for every PCI device.
In that case you can set the latency manually:
setpci -vv -s <your device> latency_timer=<latency in hex>
e.g. 'setpci -vv -s 00:11.7 latency_timer=20'
