No such thing like `the' ethernet address. By all means, make it configurable from outside, don't try to grab a particular value inside the kernel. Otherwise, if the user re-arranges his ethernet cards etc., he's at a loss. Even an ugly `gdb -k -w' trick would be better. > Soren seems to have decided to preempt me again, so I'll just wait and > see 8) So my comments hold valid for him as well. :^) -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
