igb_get_fw_version(9)

💖 igb_get_fw_version(9) 💖

okay bestie, welcome to the Kernel API Manual entry for igb_get_fw_version — yes it's a real one, yes it lives in the kernel, and yes we're gonna get through it together 🫶

---

✨ NAME ✨

igb_get_fw_version — get that firmware version info, literally what it says on the tin 💅

---

🌸 SYNOPSIS 🌸

void igb_get_fw_version (struct e1000_hw *hw , struct e1000_fw_version
*fw_vers );

like… it returns void, she's not giving you a return value, she's giving you output through a pointer. main character energy honestly 👑

---

🎀 ARGUMENTS 🎀

• hw — pointer to the HW structure 🖥️ like, the hardware context, hand her over
• fw_vers — pointer to output structure 📝 this is where the version info lands, so make sure it's real and not NULL, iykyk

---

🦋 DESCRIPTION 🦋

so here's the tea: if you hit it with an unsupported MAC type, it'll return an all-0 version structure. like the whole thing is zeros. no version, no info, just vibes and emptiness 💀 that's not a bug, that's the documented behaviour, periodt.
