You're going to need to provide output from the following, run as root.
For the pciconf command, please only include the entry that's relevant
to the device in question (em2). You can also XXX-out the MAC address
and/or IP addresses if you're worried about security.
$ pciconf -lvc
$ dmesg | grep em2
$ sysctl dev.em.2
$ uname -a
$ netstat -ind -I em2
