BSD-licensed drivers are either freely ported between the various members of the *BSD family, or used as the basis for a new platform-specific driver. The latter is required given that not all family members sport loadable kernel modules, or have compatible threading models.
Both wired & wireless network drivers frequently start in one project before getting ported to the others.
The developers
(at least in OpenBSD...) frequently know what has been checked into family member source repositories.
