No. FreeBSD has no concept of many of the architectures we support.

And for some we support that FreeBSD does not, we have our own
optimized versions thanks to years of the IPV4 stack.

We could specifically important is "default" or something and make
architectures without specific support use that single copy. Then
there is only the knowledge that we picked X to be the default
implementation.

Ultimately, you have to have an implementation. When there is not
one, we have to provide a reasonable implementation in C. And we
will always have architectures in this boat.
