The vboxnetadp.ko is needed for the "host-only adapter" mode, I tend not to
load it. For bridged mode, you need vboxnetflt.ko.
I have been having good luck by always loading vboxnetadp.ko manually rather
than from loader.conf.

I do not use a tap device. It should not be needed. I bridge the physical
device directly.

The modules are a somewhat temperamental. When I follow the above, it works
great. When I deviate, I sometimes have trouble.
