hns_mac_need_adjust_link(9)

📦 version 7.3.1, in nixpkgs unstable

okay so bestie, welcome to the hns_mac_need_adjust_link(9) page 💖 this is a kernel API manual entry and it's short, it's sweet, and it's lowkey doing exactly one job. Let's get into it ✨

✨ NAME ✨

hns_mac_need_adjust_link — check is need change mac speed and duplex register 🦋

like, the whole function is a vibe check for whether the mac speed and duplex register needs adjusting. that's it. that's the post. no cap.

🌸 SYNOPSIS 🌸

bool hns_mac_need_adjust_link (struct hns_mac_cb *mac_cb , int speed ,
       int duplex );

so it returns a bool (yes/no, iconic), it's called hns_mac_need_adjust_link, and it takes three things — a struct hns_mac_cb * named mac_cb, an int named speed, and an int named duplex. yes the spacing is exactly like that in the original, we don't touch the code, that's the law 💅

🎀 ARGUMENTS 🎀

  • mac_cb — the mac device, she's the main character of this call 🫶
  • speed — the phy device speed, i.e. the number you're bringing in for the vibe check ⭐
  • duplex — the phy device duplex, same energy, second number, also getting checked 🔥

that's the full roster. three arguments. no surprises. periodt.

first up, the actual kernel file this lives in — go read the source, it's giving lore:

quick reminder bestie: this page is a short one — the NAME line is the entire description we've got, so don't go assuming extra behaviour that isn't written here. if you need more, the source file above is right there 👑

and that's a wrap, babe 🎀 this page came from the kernel file path starting ./drivers/net/ethernet/hisilic... and it's dated October 2026 — yes, future energy, she's ahead of her time 💀✨ mwah, go debug something iconic 🦋
