Title:
Losing port aggregate with 802.3ad port-channel/bonding aggregation on
reboot
Status in linux package in Ubuntu:
Incomplete
Bug description:
The exactly the same behavior is observed when upgrade kernel to
4.15.0-123-generic.
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1834322
If we do 'ip link set dev bond2 down' and 'ip link set dev bond2 up',
the port with the mismatched ID appears to renegotiate with the port-
channel and becomes aggregated.
