I suspect "The bhyve(8) utility had support for large IOs fixed in nmve(4) emulation." refers to a change from errata 'FreeBSD-EN-21:25.bhyve' and should be nvme instead of nmve. If referring to something else with nmve, its manpage is not linking.

Correct! That's my quick typing going a little too fast and then not catching it when viewing the diff. I have pushed a fix to the website, thank you for reporting my mistake!
