Right, the problem is what I assumed: the re(4) driver in 8.1 binds to the card, but the card/driver/network layer is not functional. This means the code in 8.1 probably does not work with this revision (not "model"!) of card. If it's possible for you to get dmesg(8) output from the machine, that would be useful. Chances are there is something being emitted during kernel boot when re(4) is initialised that indicates failure. It would also help if you could provide "pciconf -lvcb" output; note the additional flags. The BAR details are sometimes useful. > is it possible to use if_re from 8.2 in 8.1 ? I would strongly recommend you avoid doing this unless the existing maintainer of re(4) says it's okay. You should not get in the habit of doing this; there is no guarantee it will work (kernel ABI structures and semantics can/do change between versions). You might be able to take the re(4) source code from 8.2 and make it compile 8.1. I don't know if you'll be able to, say, steal if_re.ko from an 8.2 mirror site and load that on 8.1. It may load, but it may not work correctly.
