ixgbe_sfp_link_config(9)

📦 version 7.3.1, in nixpkgs unstable

okay so real talk: this is ixgbe_sfp_link_config, straight out of the Kernel API Manual, section 9. It's a kernel function, not a command, so no you cannot just type it into your terminal bestie — but it's still lowkey iconic and we're gonna learn it together 🫶

✨ NAME ✨

ixgbe_sfp_link_config — set up SFP+ link

like, that's the whole job. setting up the SFP+ link. main character energy fr 💅

🦋 SYNOPSIS 🦋

void ixgbe_sfp_link_config (struct ixgbe_adapter *adapter );

that's it. that's the vibe check. one function, one argument, zero drama ✨

🎀 ARGUMENTS 🎀

  • adapter — pointer to private adapter struct

that's the one (1) thing you hand it: a pointer to the private adapter struct 🫶 the function does not want a snack, does not want your playlist, just the adapter pointer. periodt.
