This means that we will not have to have a bpf and a non-bpf version of our driver modules. This does not open any security hole, because the bpf core isn't loadable The drivers left unchanged are the "cross platform" drivers where the respective maintainers are urged to DTRT, whatever that may be. Add a couple of missing FreeBSD tags.
