Path MTU Discovery at IP level, different net namespace has
various requirements on which one to chose, e.g., a virutalized
container instance would require TCP PMTU to probe an usable
effective mtu for underlying tunnel, while the host would
employ classical ICMP based PMTU to function.
Hence making TCP PMTU mechanism per net namespace to decouple
two functionality. Furthermore the probe base MSS should also

incorrectly returns a SYN-ACK with a Fast Open cookie and also

# bridge fdb show brport eth0 | grep 12:34:56:78:90:ab
12:34:56:78:90:ab dev eth0 vlan 1 static
We expect a non-vlan fdb entry as well as vlan 1:

To fix this, we need to insert a non-vlan fdb entry if vlan is not
specified, even when any vlan is configured.
