igb_sw_init(9)

💖 igb_sw_init(9) — Kernel API Manual, but make it cute 💖

Okay so bestie, welcome to the igb_sw_init(9) page from the Kernel API Manual. This is the igb init lore you asked for, and it’s giving “setup era” energy. 🦋

✨ NAME ✨

igb_sw_init — initialize general software structures (struct igb_adapter). No cap, that’s the whole name section, but keep reading because the details are cute and important. 💅

🎀 SYNOPSIS 🎀

int igb_sw_init (struct igb_adapter *adapter );

That’s the signature, character for character. Slay. ✨

🦋 ARGUMENTS 🦋

• adapter — the board private structure to initialize, bestie. This is the thing getting set up. 🫶

🌸 DESCRIPTION 🌸

igb_sw_init initializes the Adapter private data structure. The fields are initialized based on PCI device information and OS network device settings (MTU size). So yes: PCI device info is in the mix, and the OS network device settings are in the mix too, including MTU size. It’s literally that. 🔥
