ixgbe_read_vflinks(9)

💖 ixgbe_read_vflinks — the Kernel API Manual tea ☕

okay so bestie, welcome to ixgbe_read_vflinks(9) — yes that means it's a section 9 kernel API page, and yes it's exactly as niche as it sounds. This little icon lives in the Intel ixgbevf driver world and does one (1) thing: it reads the VFLINKS register. That's it. That's the whole gig. 👑

---

✨ NAME ✨

ixgbe_read_vflinks — Read VFLINKS register 🎀

no cap, that's literally the tagline. short, sweet, slay.

---

🌸 SYNOPSIS 🌸

void ixgbe_read_vflinks (struct ixgbe_hw *hw , ixgbe_link_speed *speed ,
bool *link_up );

that's the whole signature, copy-pasted with love, spaces and all 💅

---

🦋 ARGUMENTS 🦋

• hw — pointer to the HW structure. like, the hardware mood board. you hand it over, it gets read from 🫶
• speed — link speed. the output goes here, so this is where the speed lore gets stored ✨
• link_up — indicate if link is up/down. yes it's a bool *, and yes it tells you whether the link is vibing (up) or not (down) 💀

---

💜 DESCRIPTION 💜

okay so here's the plot: this function gets the linkup status and the link speed from the VFLINKS register. that's the whole main character moment. link up? link down? speed? all from VFLINKS. periodt. 🔥

no extra steps, no mystery, no surprise twists — just VFLINKS reads and hands you the answer through speed and link_up. iconic behaviour honestly.

🫶 tiny sign-off because the footer deserves its moment too: this page is sourced from ./drivers/net/ethernet/intel/i... (yes, truncated exactly like that, blame the terminal width 😭) and it's dated October 2026. so go forth, read your VFLINKS, and stay slaying 💖🎀🌸
