This change looks unnecessary to me. The very same MAC-Address should be 
already assigned via the dts:

88 &ethernet {
89         mtd-mac-address = <&factory 0x4>;
90 };

As far as I remember, the WAN MAC-Address is only set because the switch 
driver autoincrements the base MAC-Address for the second vlan (if not 
for each vlan). Hopefully I don't mix the different switch drivers here, 
at least one of the ramips switch driver does this autoincrement.

Long story short, I either fail hard or this change triggers something 
else which fixes your customers issue.
