rio_std_route_add_entry(9)

✨ NAME ✨

okay so bestie, this is rio_std_route_add_entry from the Kernel API Manual — it's literally the function that adds a switch route table entry using the standard registers defined in the RIO specification rev.1.3. no cap, that's the whole vibe. 💅

🌸 SYNOPSIS 🌸

int rio_std_route_add_entry (struct rio_mport *mport , u16 destid , u8
hopcount , u16 table , u16 route_destid , u8 route_port );

🎀 ARGUMENTS 🎀

• mport — the master port that's gonna issue the transaction, periodt. 🫶
• destid — destination ID of the device. the whole point, fr fr.
• hopcount — number of switch hops to the device. how many jumps, bestie. 🦋
• table — routing table ID (global or port-specific). choose your fighter. ✨
• route_destid — destID entry in the RT. the routing table said yes. 🔥
• route_port — destination port for specified destID. that's the exit, slay. 🎯
