I see. Getting back to this case, I am using MAC names, since that's
what mac_init_prop() can easily derive from {devinfo,instance} and use
internally to associate properties with. The userland (dlmgmtd,
libdladm) should have no problem finding properties based on MAC name.
So MAC passes the name to dlmgmtd via upcall and dlmgmtd bounces it
right back to MAC (via DLD) with some properties attached to it. Feels
pretty organic to me.
