Bug description:
We are losing port channel aggregation on reboot.
After the reboot, /var/log/syslog contains the entries:
[ 250.790758] bond2: An illegal loopback occurred on adapter (enp24s0f1np1)
Check the configuration to verify that all adapters are
connected to 802.3ad compliant switch ports
[ 282.029426] bond2: An illegal loopback occurred on adapter (enp24s0f1np1)
Check the configuration to verify that all adapters are
connected to 802.3ad compliant switch ports
Aggregator IDs of the slave interfaces are different:

The mismatch in "Aggregator ID" on the port is a symptom of the issue.
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.
The other way to workaround this issue is to put bond ports down and
bring up port enp24s0f0np0 first and port enp24s0f1np1 second.
When I change the order of bringing the ports up (first enp24s0f1np1,
and second enp24s0f0np0), the issue is still there.
When the issue occurs, a port on the switch, corresponding to
interface enp24s0f0np0 is in Suspended state. After applying the
workaround the port is no longer in Suspended state and Aggregator IDs
in /proc/net/bonding/bond2 are equal.
I installed 5.0.0 kernel, the issue is still there.
