After (re)assigning the interfaces at the console following a mismatch the WAN interface triggers a number or scripts. Some of which now send output to the console:

Network interface mismatch -- Running interface assignment option.
alc0: link state changed to DOWN
mlx4_en: mlxen0: Fail to add unicast address
mlx4_en: mlxen1: Fail to add unicast address

Valid interfaces are:

alc0    6c:f0:49:cb:40:7a (down) Atheros AR8131 PCIe Gigabit Ethernet
mlxen0  00:02:c9:09:89:c0 (down) 
mlxen1  00:02:c9:09:89:c1 (down) 

Do VLANs need to be set up first?
If VLANs will not be used, or only for optional interfaces, it is typical to
say no here and use the webConfigurator to configure VLANs later, if required.

Should VLANs be set up now [y|n]? 
alc0: link state changed to UP

If the names of the interfaces are not known, auto-detection can
be used instead. To use auto-detection, please disconnect all
interfaces before pressing 'a' to begin the process.

Enter the WAN interface name or 'a' for auto-detection 
(alc0 mlxen0 mlxen1 or a): 
Enter the LAN interface name or 'a' for auto-detection 
NOTE: this enables full Firewalling/NAT mode.
(mlxen0 mlxen1 a or nothing if finished): 
The interfaces will be assigned as follows:

WAN  -> alc0

That did not happen in 2.4.X. It doesn't appear to cause a problem but is ugly/confusing.

In addition you can see it loops back around configuring all the inetrface types twice for some reason.

Tested in 2.5-rel and 21.02-rel. This also affected earlier RC snapshots.
