: 
: Interface0_addr="MAC 01:23:45:67:89:ab"
: Interface1_addr="PCI 0:1:2"		# pci0, device 1, function 2
: Interface2_addr="USB 0:1:2"		# usb0, addr 1, port 2

: Add some bits to grok dmesg or pciconf/usbdevs or maybe even trigger from 
: devd and there you go.

: I should mention that the second and third options could be broken by the
