idpf_set_msglevel(9)

🌸 idpf_set_msglevel — it's giving "Kernel API Manual" energy ✨

okay bestie, so this one's a lil function called idpf_set_msglevel, and it lives in the Kernel API Manual. it's short, it's sweet, it slays. let's get into it 💅

---

🎀 SYNOPSIS 🎀

void idpf_set_msglevel (struct net_device *netdev , u32 data );

literally that's it. that's the whole vibe check. no cap. 🦋

---

✨ ARGUMENTS ✨

• netdev — the network interface device structure, aka the whole entire device's ~identity~ 🫶
• data — the message level, like, the volume knob but for debug messages 🔊

---

💖 DESCRIPTION 💖

So what it does is: it sets the current debug message level. and here's the iconic part — higher values cause the driver to be noisier. noisier!! like it's at a sleepover and someone brought snacks and the tea is SPILLING 🍓🔥

so yeah. low value = chill quiet driver. high value = the driver will NOT stop talking. choose your fighter. 💀
