Summary:                    [patch] adding ss7 pcap support to dahdi
Description: 
as per the thread on the libss7 mailing list

1. changes to the dahdi driver to add ioctls to mirror reads/writes
from a signaling channel to a pseudo channel
2. a corresponding user app to set up the mirroring and record the
traffic in a pcap

This seems to work though I'm not sure if it's the best solution
design-wise.
I might be abusing the pseudo channel concept.

to compile the app do the following
gcc dahdi_pcap.c -o dahdi_pcap -lpcap

and the syntax to run it is
./dahdi_pcap chan1  [chan2]* pcap.pcap

e.g.
./dahdi_pcap 16 47 test.pcap

Hi,
I've implemented options now as well as solved some compiler warnings. The
result is uploaded as dahdi_pcap-v5.c as well as a patch which also include
the changes needed for makefile. This is the usage:

Usage: dahdi_pcap [OPTIONS]
Capture packets from DAHDI channels to pcap file

Options:
  -p, --proto=[mtp2|lapd] The protocol to capture, default mtp2
  -c, --chan=<channels>   Comma separated list of channels to capture
from, max 16. Mandatory
  -f, --file=<filename>   The pcap file to capture to. Mandatory
  -h, --help              Display this text
