Comment (by nbd):
So here's what happens:
netifd relies on the ppp-up and ppp-down script to notify it about
interface state changes. pppd first brings up ipv4 and ipv6, calls ppp-up
for both.
Then your ISP terminates the ipv6 session, and pppd calls ppp-down for
ipv6. This script tells netifd that the interface is down now (since it
doesn't know that only one session died, not both).
So netifd considers the interface disabled from now on.
Disabling ipv6 should prevent this issue, and I'm currently thinking
whether it makes sense to simply not pass ipv6 down events to netifd at
all.
