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

tsearle:  Yes, but perhaps that shouldn't be the case when digitally
monitoring the channel.  However,  I see what you're saying and understand
why you added the mirroring IOCTLS.

I'll see if it's possible to tweak things in order to get the data from
the signaling channel without adding a new concept to the interface but
I'll probably need to go through the exercise at this point before I can
debate any relative merits with you :)
