👑 DESCRIPTION 👑

So here's the vibe: netlbl_mgmt_listdef processes a user generated LISTDEF message, and then dumps the default domain mapping in a form suitable for use in a kernel generated LISTDEF message ✨ like, she takes the user's ask and repackages the default domain mapping so the kernel can spit out its own LISTDEF with it. lowkey iconic.

Return value tea ☕: she returns zero on success, and negative values on failure 😭 so if you see a negative number, something went off and that's your vibe check failing.
