Subject: pppoe-discovery: use correct exit code depending on PADO replies.
X-Git-Tag: ppp-2.4.8~31^2~2
X-Git-Url: http://git.ozlabs.org/?p=ppp.git;a=commitdiff_plain;h=bb65ff8830596e22d5f6c4c66274ddd726545c85

pppoe-discovery: use correct exit code depending on PADO replies.

This makes it possible to evaluate the exit code of the tool,
e.g. if you just want to know if there is an access concentrator
or not.
