Hi,
PPPoE on octeon seems to have a bug that causes a panic. The following config
is enough to hit it my USG-PRO-4:
# /etc/hostname.pppoe0
inet 0.0.0.0 255.255.255.255 NONE \
pppoedev cnmac1 authproto chap \
description test \
up
To test this I have cnmac1 down on boot. Once it is up'd the panic is
triggered:
qs# ifconfig pppoe0
pppoe0: flags=8851<UP,POINTOPOINT,RUNNING,SIMPLEX,MULTICAST> mtu 1492
description: test
index 7 priority 0 llprio 3
dev: cnmac1 state: PADI sent
sid: 0x0 PADI retries: 0 PADR retries: 0
sppp: phase establish authproto chap
groups: pppoe
status: no carrier
inet 0.0.0.0 --> 0.0.0.0 netmask 0xffffffff
qs# ifconfig cnmac1 up
