💅 ksz88x3_tc_ets_del(9) 💅

okay so bestie, we're deep in the Kernel API Manual today and the star of the show is ksz88x3_tc_ets_del — yes that's a mouthful, yes it's iconic, and yes it resets the ETS (Enhanced Transmission Selection) config for a port on a KSZ88x3 switch. let's get into it 🎀

✨ NAME ✨

ksz88x3_tc_ets_del — reset ETS (Enhanced Transmission Selection) config for a port on KSZ88x3 switch 🌸

---

🦋 SYNOPSIS 🦋

int ksz88x3_tc_ets_del (struct ksz_device *dev , int port );

---

👑 ARGUMENTS 👑

• dev — pointer to the KSZ switch device structure. she's the main character of the whole thing 🫶
• port — the port number to reset. like, the specific little port we're giving a glow-up reset to 💅

---

💖 DESCRIPTION 💖

so the tea is this: the KSZ88x3 literally only supports fixed scheduling modes — that's Strict Priority or Weighted Fair Queuing (WFQ). no reconfiguration of weights, no queue mapping, none of that. it's giving "we have exactly two modes and we're sticking to them" 💀

what this function does is reset the port's scheduling mode back to the default, and that default is WFQ — it does this by enabling the WFQ bit for all queues. so yeah, every queue gets that WFQ treatment. slay 🦋

---

⭐ RETURN ⭐

0 on success, or a negative error code on failure. that's it, that's the vibe check 😭
