netdev_get_msglevel(9)

💖 netdev_get_msglevel(9) 💖

okay so this little icon is straight out of the Kernel API Manual and honestly? she's a one-job queen and she does that job flawlessly. no cap. let's get into it 💅

---

🎀 NAME 🎀

netdev_get_msglevel — get debug message level ✨

---

✨ SYNOPSIS ✨

u32 netdev_get_msglevel (struct net_device *dev );

like, that's it. that's the whole vibe. one arg, one u32 back 🫶

---

🫶 ARGUMENTS 🫶

• dev — Network device. that's the one (1) thing you hand her, and she takes it from there, bestie 🦋

---

💅 DESCRIPTION 💅

so what does she do? This function returns current debug message level. iconic behavior, honestly.

Return current debug message flags. periodt. that's the entire personality 🌸

ngl the description is short but the confidence is loud. she said "current debug message level" and she meant it 💀
