if every bhyve guest ever is going to need this, then the interface
offered to the guest kernel ought to present the right set of defaults
to cause the right choice to be made, or the guest kernel must simply
"know better". in other words me adding something to /boot/loader.conf
or /etc/sysctl.conf in every single bhyve guest ever is an indication
that we're doing something wrong elsewhere.
