How does one specify a 'symbolic' name for an ethernet interface; i.e. be able to refer to rl0, vx1 or ep0 by a name like 'net0, net1' or 'net2'. With net1 et.al. tied to a specific PCI slot or card Mac address. So that it becomes easier to write HW independed rc.conf or zebra.conf files. Thanks. Dw
