pch_gbe_ioctl(9)

💖 pch_gbe_ioctl — the Kernel API Manual moment ✨

okay so bestie, welcome to pch_gbe_ioctl(9), a Kernel API Manual entry, and honestly it's giving "small function, big responsibilities" 🎀

---

✨ NAME ✨

pch_gbe_ioctl — controls register through a MII interface 🦋

like, yes, that's the whole pitch. it pokes at registers via the MII interface, iykyk 💅

---

🌸 SYNOPSIS 🌸

int pch_gbe_ioctl (struct net_device *netdev , struct ifreq *ifr , int
cmd );

that signature is literally the whole vibe. three args, one int coming back at you 🫶

---

🧚 ARGUMENTS 🧚

• netdev — the network interface device structure. it's the whole NIC's main character energy, no cap 👑
• ifr — a pointer to the ifr structure. yes, a pointer. we love a pointer 💜
• cmd — the control command. this is what tells the function what to actually do, iconic behavior ⭐

---

🔥 RETURN 🔥

• 0 — successfully 🎉 slay, it worked
• Negative value — failed 😭 not the vibe, something went sideways

bestie note: the manpage says "Successfully Negative value: Failed" — so like, 0 = good, anything negative = bad news bears 💀
