e1000_shift_in_mdi_bits(9)

💅 e1000_shift_in_mdi_bits(9) — the Kernel API Manual, bestie edition

okay so picture this: we're deep in the e1000 driver, and this little function — e1000_shift_in_mdi_bits — is the one that clocks data bits in from the PHY. It lives in the Kernel API Manual, and honestly? It's giving "tiny function, big job." 🎀

✨ NAME ✨

e1000_shift_in_mdi_bits — shifts data bits in from the PHY. That's it, that's the whole vibe. 🦋

---

🌸 SYNOPSIS 🌸

u16 e1000_shift_in_mdi_bits (struct e1000_hw *hw );

no cap, that's the whole signature. returns a u16, takes one pointer. iconic. 👑

---

🎀 ARGUMENTS 🎀

• hw — a pointer to the struct containing variables accessed by shared code. like, the whole shared-code brain of the driver lives in there. 🧠✨

---

💖 DESCRIPTION 💖

So here's the tea: bits get shifted in MSB to LSB order. Most-significant bit first, least-significant bit last. that's the entire description, and honestly it ate. 🫶

💜 sign-off 💜

this page came from ./drivers/net/ethernet/intel/e... and it's dated October 2026 — so yeah, straight from the Kernel API Manual, e1000_shift_in_mdi_bits(9) flavored. go shift some bits, bestie. MSB first. 💅✨💖
