🦋 rio_update_route_tables 💅

okay so this is a page straight out of the Kernel API Manual, and bestie, we are getting into RapidIO routing business ✨ — it's giving "plumbing but make it kernel", and honestly? obsessed.

🌸 NAME 🌸

rio_update_route_tables — the function that goes in and updates route tables in switches, no cap 🔥

---

⭐ SYNOPSIS ⭐

void rio_update_route_tables (struct rio_net *net );

literally that's the whole signature. simple. iconic. periodt 💜

---

🎀 ARGUMENTS 🎀

• net — the RIO network you wanna run the update on, bestie. that's the vibe check target 🌈

💖 DESCRIPTION 💖

so here's the tea 🍓: for each enumerated device, this function makes sure that each switch in a system has the correct routing entries. like, every switch gets its routes checked and fixed up, no device left looking confused 😭

and then — the main character move — it adds routes for devices that were unknown during the first enumeration pass through the switch. yep, the first pass missed them, so this is the second pass coming in to fix it. glow-up round two ✨💅
