It looks like bnxt actually has a hardcoded offload of the Geneve port
rather than using the registration (maybe it predated it?). It would
be nice to incorporate that into your unified handler as well.

I think you could actually just kill all of these
CONFIG_VXLAN/CONFIG_GENEVE checks (across all the drivers, not just
this one). They shouldn't be necessary any more now that there's no
longer strong linkage to the tunnel drivers.
