stmmac_ioctl(9)

💅 stmmac_ioctl(9) 💅

okay bestie, welcome to the Kernel API Manual ✨ this one's short and sweet — literally the door greeter for ioctls. let's get into it 🫶

---

✨ NAME ✨

stmmac_ioctl — the entry point for the Ioctl 💫 like, the one function everything knocks on the door first.

---

🌸 SYNOPSIS 🌸

int stmmac_ioctl (struct net_device *dev , struct ifreq *rq , int cmd );

that's the whole vibe check right there 💅

---

🎀 ARGUMENTS 🎀

• dev — the device pointer. yeah. just… the device 💖
• rq — an IOCTL specific structure, and lowkey the fun one — it can hold a pointer to a proprietary structure that's used to pass info along to the driver 👀 iykyk
• cmd — the IOCTL command itself ⭐

---

🦋 DESCRIPTION 🦋

so basically it forwards the PHY ioctls to phylink 🧚 that's it. that's the whole job. it's giving middle-manager energy but in the slay way.

---

💜 RETURN 💜

zero on success 🎉 or a negative error code 😭 (bestie we've all been there)

💀 real talk: no warnings, no deprecated options, no exit status weirdness on this page. it's just a chill little forwarding function. love that for us 🍓
