dhcp6c@pppoe0.service cannot stop gracefully when VyOS shutdowns
Closed, ResolvedPublicBUG

Description

When configuring a pppoe interface with dhcpv6-pd, it costs more time for VyOS to reboot/shutdown since dhcp6c@pppoe0.service cannot stop gracefully when VyOS shutdowns. The systemd unit waits for 30s to be killed.
The bug is due to wrong order of dhcp6c@pppoe0.service and ppp@pppoe0.service. When shuting down, the ppp@pppoe0.service exits immediately so the pppoe interface is down. But without interface pppoe0, dhcp6c@pppoe0.service cannot stop.
