e1000_get_link_up_info_vf(9)

📦 version 7.3.1, in nixpkgs unstable

okay so real talk, this is a page from the Kernel API Manual, and the function we're stanning today is e1000_get_link_up_info_vf — yes it's a mouthful, yes it slaps, let's get into it bestie ✨

🌸 NAME 🌸

e1000_get_link_up_info_vf — it gets link info, that's literally the whole vibe 💅

🦋 SYNOPSIS 🦋

s32 e1000_get_link_up_info_vf (struct e1000_hw *hw , u16 *speed , u16
*duplex );

like, that's the signature, copy it exactly please, no cap 🫶

🎀 ARGUMENTS 🎀

  • hw — pointer to the HW structure. your main character struct fr 🧚
  • speed — pointer to a 16 bit value where the link speed goes. it's storage, it's giving empty locker energy, it's ready to be filled 💖
  • duplex — pointer to a 16 bit value to store duplex. same deal, 16 bits of duplex-shaped space ⭐

✨ DESCRIPTION ✨

okay so here's the situation and it's lowkey a little tragic 😭 we literally cannot read the PHY to get accurate link info — not an option, not happening. so instead we have to rely upon the status register's data, which, and I cannot stress this enough, is often stale and inaccurate. like we're out here doing our best with secondhand tea, ngl. the register said what it said 🙈
