Package: ifupdown-extra
Version: 0.32
Severity: important
Tags: patch
Dear Maintainer,
/usr/sbin/arping from `arping` package uses '-d' option to detect duplicates,
not '-D'. I fixed it in the provided patch (also took the liberty to fix the
case for the interface flag).
Also, the default ARP_TIMEOUT set in /etc/default/network-test renders
ineffective the specific setting of 1500 ms for it in the script, which should
be at least noted in the comments or README.
