xgmac_open(9)

💖 xgmac_open(9) — like, the driver's open era 💖

okay bestie, welcome to the Kernel API Manual, and today's main character is xgmac_open — literally the open entry point of the driver. yes, that's her whole job. she opens. she slays. no cap. ✨

---

✨ SYNOPSIS ✨

int xgmac_open (struct net_device *dev );

that's the whole signature, verbatim, don't @ me. 🫶

---

🎀 ARGUMENTS 🎀

• dev — pointer to the device structure. that's it. that's the argument. she just needs the struct net_device * and she's good to go 💅

---

🌸 DESCRIPTION 🌸

okay so real talk: this function is the open entry point of the driver. like, when the driver needs to, yk, open, this is the girl doing it. main character energy fr fr. 👑

and about the return value (because you know she reports back):

• 0 on success — icon status, we love a clean zero 🌈
• an appropriate (-)ve integer as defined in the errno.h file on failure — yes bestie, negative, as in the errno.h header file, that's literally where those values live, don't make me say it twice 😭

so like... zero? slay. negative? something went wrong and errno.h already has the receipts. 🧾💀
