e1000_set_la...ti_port_pcie(9)

👑 e1000_set_la...ti_port_pcie(9) — a Kernel API Manual moment

okay so bestie, welcome to the manual of e1000_set_la...ti_port_pcie(9) 💅 yes that's the whole vibe, it's a kernel API manual page and it's about to explain one (1) function to you. she's niche, she's specific, she's lowkey iconic. let's go 🦋

---

✨ NAME ✨

e1000_set_lan_id_multi_port_pcie — sets the LAN id for PCIe multiple port devices 🌸

like... that's her whole job. that's the assignment and she ate.

---

💜 SYNOPSIS 💜

void e1000_set_lan_id_multi_port_pcie (struct e1000_hw *hw );

no return value, no drama, just vibes and a pointer 🫶

---

🎀 ARGUMENTS 🎀

• hw — pointer to the HW structure. that's it. that's the whole argument list. one (1) pointer and she's set 🙈

---

🔥 DESCRIPTION 🔥

okay so here's the tea ☕ — this function figures out the LAN function id by reading memory-mapped registers, and then, if it's requested, it swaps the port value. that's literally it, that's the whole plot. determine the id, swap the port when asked, done, periodt 💅✨

ngl it's giving "small function, big responsibility" energy. main character behavior fr fr 👑

no cap: this is a void function, so don't go looking for a return value — there isn't one, bestie 😭

and that's the whole page, bestie 💖 she's short, she's sweet, she sets a LAN id. go read her friends too, iykyk 🧚⭐

before you go — the tiny fine print at the bottom of the page says the source line is ./drivers/net/ethernet/intel/e... and the date on this cutie is October 2026 📅✨ so yeah, that's the vibe, that's the footer, muah 💋🍓
