>you need to disable the PnP support for your card using the smc config
program. Linux will not support PnP. I had to do this with my 3com card
and now it sets up, however I have the same message on my machine. So
the PnP turn off won't help with the SIOCSFFLAGS message. But if you
discover the answer to this I would appriciate the answer.
