You cannot bridge via WiFi because this requires support to not
only receive for arbitrary MAC addresses but also to send from
them.

Some hardware might even allow that (it's necessary for hostap
mode), but then you need to act as multiple WiFi clients. Then
there is WDS mode (also known as 4-address mode), that lets you
act as a WiFi extender, but we don't support that either, it's also
not compatible with many access points.

I'm not sure how far PCI passthrough does work with NetBSD.
