igc_setup_link(9)

💖 igc_setup_link(9) 💖

okay so bestie, welcome to the Kernel API Manual — this is the igc_setup_link page and honestly it's giving "networking glow-up" ✨

---

🎀 NAME 🎀

igc_setup_link — setup flow control and link settings 🦋

---

✨ SYNOPSIS ✨

s32 igc_setup_link (struct igc_hw *hw );

like, that's the whole vibe. one function, one struct pointer, and yes it returns an s32 💅

---

🌸 ARGUMENTS 🌸

• hw — pointer to the HW structure 🫶 that's it, that's the argument, it's the hardware struct and she's the main character of this whole page

---

💜 DESCRIPTION 💜

so here's the tea ☕ — igc_setup_link figures out which flow control settings to use, and then it configures flow control. no cap, that's the job.

after that it calls the appropriate media-specific link configuration function ✨ (media-specific, so like, it picks the right one for the job, iykyk).

assuming the adapter has a valid link partner, a valid link should be established 🔥 — key word assuming, bestie, she's not out here guaranteeing anything.

⭐ also important: this function assumes the hardware has previously been reset and that the transmitter and receiver are not enabled. so like, do your homework first, don't just roll up 💀
