The card with the very long hardware address
(00-E0-81-00-00-30-BA-8D-00-00-00-00-00-00-00-00) is a firewire link.
You can rename your two interfaces with udev :
1 - Create a file in /etc/udev/rules.d/ (for example: 20-local.rules)
2 - Put the two following lines :
SYSFS{address}=="AB:CD:EF:12:34:56", NAME="lan0"
SYSFS{address}=="12:34:56:78:90:AB:CD:EF", NAME="fw0"
Of course, you must replace AB:CD:EF:12:34:56 and 12:34:56:78:90:AB:CD:EF by
the corresponding addresses of the cards. To do this, you can use :
# udevinfo -a -p /sys/class/net/eth0
