igc_sw_init(9)

💖 igc_sw_init(9) — like, the Kernel API Manual page, bestie 💖

okay so you found the igc_sw_init(9) page in the Kernel API Manual and you're like "what does this even do" — don't worry, I got you. this is the little setup ritual for the igc driver's adapter struct, and honestly? it's giving backstage-pass energy. 🎀

---

✨ NAME ✨

igc_sw_init — Initialize general software structures (struct igc_adapter)

like, it wakes up the software side of the adapter and gets it dressed for the day. 🦋

---

✨ SYNOPSIS ✨

int igc_sw_init (struct igc_adapter *adapter );

one function, one pointer, returns an int. simple. iconic. periodt. 💅

---

✨ ARGUMENTS ✨

• adapter — the board private structure you're initializing. this is the struct, the main character, the one we're setting up. 🫶

---

✨ DESCRIPTION ✨

so igc_sw_init initializes the Adapter private data structure. that's the whole vibe. ✨

the fields get initialized based on PCI device information and OS network device settings (that's the MTU size, bestie — Maximum Transmission Unit, iykyk). so it's pulling facts from the hardware and from whatever the OS thinks the network device looks like, then wiring up the struct accordingly. no cap, that's it. 🌸

lowkey important: this is a structure-initialization function. it doesn't invent behavior — it reads PCI device info and OS network device settings (MTU) and sets fields from those. keep that in mind and you're golden. 👑
