Try this script (untested):

--------------------------------------------
#!/bin/bash
ETH=`ifconfig | grep -i $1 | cut -d ' ' -f 1`
echo "Blinking $ETH - $1"
ethtool -p $ETH 30
--------------------------------------------

Just call it with the mac address as an argument.  It will find the
interface with ifconfig and then call ethtool to blink the lights for 30
seconds.

(Assuming your NIC supports ethtool.  The system I tried to test this on
was not supported...)
