Here's an example.

The original setup:
 
$ ifconfig -a
rl0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500
        ether 00:e0:29:85:49:b6
        media: Ethernet autoselect (10baseT/UTP)
        status: no carrier
rl1: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500
        ether 00:e0:29:85:49:d0
        media: Ethernet autoselect (10baseT/UTP)
        status: no carrier
 
After the cards are switched around in the PCI slots:
 
$ ifconfig -a
rl0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500
        ether 00:e0:29:85:49:d0
        media: Ethernet autoselect (10baseT/UTP)
        status: no carrier
rl1: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500
        ether 00:e0:29:85:49:b6
        media: Ethernet autoselect (10baseT/UTP)
        status: no carrier
 
How can I keep rl0 associated with MAC 00:e0:29:85:49:b6 
and rl1 associated with MAC 00:e0:29:85:49:d0 and still
be able to add cards or move them around?

TIA,
Terry Todd
