- pppd: Allow specifying ip-up and ip-down scripts
- This patch implements the "ip-up-script" and "ip-down-script" options which
- allow to specify the path of the ip-up and ip-down scripts to call.
- These options default to _PATH_IPUP and _PATH_IPDOWN to retain the
- existing behaviour.
- The patch originated from the Debian project.
