A possible usage scenario is where you do massive imaging of a freebsd installation in where you don't know beforehand it will end up on hardware that has Broadcom or Intel NICs but it is for certain the cable will be connected to the first interface available and the same interface name can be referenced throughout all configuration files that need it (pf.conf, rc.conf(.local), /etc/rc.conf.d/network ) An other application usage is nailing down interface names using ethernet address, either because of correcting "mistakes" in the hardware (e.g. some Dell PowerEdges have the port labelled first to be probed as second and vice versa) or the necessity to only allow that interface to exist if it's MAC is the one that was configured (because of switch port ACL's) Regards, Ruben
