emac_devioctl(9)

💅 emac_devioctl(9) — like, the EMAC adapter ioctl, bestie

okay so this is a page straight out of the Kernel API Manual, and it's about emac_devioctl — the EMAC adapter ioctl. yes that's the whole vibe. it's short, it's sweet, it's giving "function that just does its job and leaves" ✨

---

🌸 NAME 🌸

emac_devioctl — EMAC adapter ioctl. that's it. that's the whole name. iconic minimalism honestly 🎀

---

🦋 SYNOPSIS 🦋

int emac_devioctl (struct net_device *ndev , struct ifreq *ifrq , int
cmd );

so it takes three things and hands you back an int, no cap 💖

---

✨ ARGUMENTS ✨

• ndev — The DaVinci EMAC network adapter. this is the main character right here 👑
• ifrq — request parameter. yes that's the whole description, she's mysterious like that 🙈
• cmd — command parameter. also keeping it lowkey vague, we love a cryptic queen 💅

---

🔥 DESCRIPTION 🔥

so this is the EMAC driver ioctl function. that's the entire flex. it handles the ioctl stuff for the EMAC driver and that's literally it 🫶

it Returns success(0) or appropriate error code. so like, 0 means slay ✅, and anything else is the universe telling you something went wrong 😭

ngl the manpage is kinda sparse on details here, so don't go inventing behaviour — what you see is what you get 💀

and that's the page!! mwah 💋 ok so the source path is ./drivers/net/ethernet/ti and this whole thing is dated October 2026, which is honestly so far away it's giving time traveler energy ⭐ bye bestie, go write some ioctl code 🧚‍♀️🎀
