Summary:                    dahdi_test accurately reports nonsense
Description: 
dahdi_test reports -200% or 400% accuracy.

That's clearly stupid.

Also, the percentage printed in verbose mode clearly doesn't match the one
printed in terse mode.

SVN trunk as of last week.

# dahdi_test -v& sleep 6; killall dahdi_test

Hmm, isn't that what "dahdi_test -c5" is supposed to do? ;-)

Anyway:

root at lab:~# dahdi_scan 
[1]
active=yes
alarms=UNCONFIGURED
description=DAHDI_DUMMY/1 (source: HRtimer) 1
name=DAHDI_DUMMY/1
manufacturer=
devicetype=DAHDI Dummy Timing
location=
basechan=1
totchans=0
irq=0
root at lab:~# 

So it seems that a broken patch in my build script mistakenly enabled
dahdi_dummy, and that dahdi_dummy is currently not only out-of-date but
broken. My bad.

root at lab:~# rmmod dahdi_dummy
root at lab:~# dahdi_test -v -c5
Opened pseudo dahdi interface, measuring accuracy...

OK, so now please fix the "Difference:" part of the result. :-P
