I'm installing MAAS 3.0 (regiond+rackd) on a HPC management node (Ubuntu 18.04）. The infiniband network interfaces immediately caused some problems because its MAC-address is 20-octet long, not 6-octet long. But the MAAS DB uses type macaddr for column mac_address in table maasserver_interface, which assumes 6-octet.

Is there a way to restrict the network interfaces that maas will read? To exclude infiniband intefaces (ib0 & ib1 in my case), for example.
Or I suggest the MAAS developers use a different type (character varying) for column mac_address.
Thanks
