Before the lw4o6 draft was updated to reference map-dhcp for configuration, the port configuration was described in sun-dhc-port-set-option, which also stated that the WKPs should not be assigned. This advice got lost when changing to reference map-dhcp. I’ll make a suggested text update for the lw4o6 draft to fix this.
