Tap device problem on FreeBSD 14.2-RELEASE

I used FreeBSD-update to go from 14.1-RELEASE to 14.2-RELEASE and there 
is an issue with creating and using the tap device.  The device doesn't 
get created during the boot process and can't be created or used after 
the system is up.  The UPDATING file has just one entry concerning the 
tap device and that is change the 'tap' name in all configuration files 
with 'tuntap'. I did that and get an invalid device reply.  I installed 
the latest package for vm-bhyve which did not make any difference.  I 
also deleted /usr/obj/* and checked out a fresh /usr/src and rebuilt 
FreeBSD-14.2-RELEASE from source without anything working differently.

If anyone has a working tap device using FreeBSD 14.2-RELEASE, I would 
appreciate you sharing your bhyve portions of /etc/rc.conf, 
/etc/sysctl.conf and /boot/loader.conf files.

Thanks

Tom
