- Use netifd no_proto_task for notifying that xl2tpd does not have a
protocol task running.
- Use procd for xl2tpd service management.
- Refreshed 2xx patches to
- Prevent leftover regular type control result file.
- Allow xl2tpd run as foreground process while logging via syslog.

- bumped version
- removed dependency on `ip` package as routes are setup by netifd
if iproute2 is actually required, please depend on
`@(PACKAGE_ip||PACKAGE_ip-full)` instead of `ip`

Subject: [PATCH 206/210] xl2tpd: start_pppd: place opts after "plugin
|
|
pppol2tp.so".
|
|
|
|
so that plugin options like pppol2tp_debug_mark can be recognized by
|
|
pppd. While doing this also add bound check to prevent potential buffer
|
|
overflow problem.
