Let's keep this thread focused on the issue you originally reported, re:

Open up another separate thread (don't reply to this one and start a new
topic; send a brand new Email) for whatever issues you're having with
em(4).  In *that* thread, provide output from:

- uname -a  (you can X-out the machine name if need be)
- dmesg | grep em0  (or whatever interface number, e.g. em2)
- pciconf -lvc
