       destid , u8 hopcount , u32 *rmap );

🎀 ARGUMENTS 🎀

• port — the master port you're issuing the transaction on. main character port energy, fr fr.
• local — indicates a local master port or a remote device access. literally the vibe check for local vs remote.
• destid — the Destination ID of the device. iykyk.
• hopcount — the number of switch hops to the device. count 'em, bestie.
