>From the beginning: I have a FreeBSD7 machine with two network cards, both carry the same device name "mtnic". My driver is a kernel module loaded manualy using kldload. Upon load, the driver registers the net device by the name "mtnic<unit number>", that is what you see in ifconfig. Problem is, this unit number is not constant and changing arbitrarily every time I reload the driver (card A unit number=0 & card B un=1 or the other way around). Therefore, IP assignment to mtnic0 by /etc/rc.conf may assign an interface with an IP belongs to another subnet, since rc.conf is not changing. Of course I can keep my own MAC-to-interface mapping and rename the interfaces after I load the driver. It doesn't sound like a reasonable solution though. Plus, I still don't understand why the unit number should change at all, instead of being determined according to the card PCI location or some other constant.
