@jow with the highest debug level for netifd the log exhibits some ominous
netifd: wan Command failed: Not found
each time ppp.sh is invoked. How to find out what it is that is not found?
Having added some addition logging to ppp.sh there is some bit of inconsistency with
/sys/class/net/eth2/operstate, shows mostly down, e.g.
kernel info on eth2 -> operstate = down | -> carrier = 1 | -> flags = 0x1003
but on some call showing
kernel info on eth2 -> operstate = up | -> carrier = 1 | -> flags = 0x1003
According to https://www.kernel.org/doc/Documentation/networking/operstates.txt
Interface is unable to transfer data on L1, f.e. ethernet is not plugged or interface is ADMIN down
And logging with each ppp.sh invocation ubus status is showing:
ubus info on wan "up": false, "pending": true, "device": "eth2"
