Marius, thanks for your answer. As far as I understand, the devinfo output will only contain useful information if a driver attaches to the phy. Sometimes a new mainboard hits the market and the ID of the phy's chip is unknown the FreeBSD. If a submitter files a PR and no phy driver attaches, I would like to check if the chip ID is currently known to the system. So I need to know a way to check the ID of a chip without a driver being attached. In short my original question better reads as "how do I know the kind of phy if no driver has been attached". Can one retrieve that information out of a verbose boot dmesg (from probing messages)? I would like to first check if a PR might be related to a phy problem at all and if it's just coming with an ID currently unknown to FreeBSD to prepare the PR into a state containing every piece of information needed to have the net-team working easily on it. Thanks Volker
