igb_setup_tctl(9)

💅 igb_setup_tctl(9) — the Kernel API Manual page, but make it make sense

okay so bestie, welcome to igb_setup_tctl(9), straight out of the Kernel API Manual ✨ this is the little function that handles the transmit control registers — like, it's the one who does the TCTL glow-up so your packets can actually go out. no cap, it's a whole vibe. 🦋

---

🌸 NAME 🌸

igb_setup_tctl — configure the transmit control registers 💌

---

✨ SYNOPSIS ✨

void igb_setup_tctl (struct igb_adapter *adapter );

she returns nothing (void, we love a low-maintenance icon) and she takes exactly one thing. periodt. 🎀

---

💖 ARGUMENTS 💖

• adapter — the board private structure. yeah that's it. that's the whole argument. it's giving "one job and she ate" 👑

ngl if you're staring at this like "wait, is that really all?" — yes bestie, that's really all. adapter is the board private structure, full stop. 💅
