✨ ice_update_tx_topo_user_sel(9) ✨

okay bestie, so this one's a kernel API manual page — the manual is literally called ice_update_tx_topo_user_sel(9) — and it's basically the "save my settings" button for your Tx topology vibes 💾💅

🎀 NAME 🎀

ice_update_tx_topo_user_sel — saves the user's preference into flash 🫶 like, it remembers what you picked so you don't have to pick it again, iconic behavior honestly

🌸 SYNOPSIS 🌸

int ice_update_tx_topo_user_sel (struct ice_pf *pf , int layers );

no cap, that's the whole signature ✨

🦋 ARGUMENTS 🦋

  • pf — pointer to the pf structure 💖 (yes, it's just a pointer to pf, that's the whole tea)
  • layers — the value that's gonna get saved in flash 🍓 this is the actual number we're committing to memory

💜 DESCRIPTION 💜

okay so the variable layers is literally defining the user's preference about how many layers live in the Tx Scheduler Topology Tree 🌈 that's the whole vibe.

and this choice should be stored in the PFA TLV field so the driver can just pick it up next time during init — like a little love note from past-you to future-driver 😭🫶

fr fr, the storing is the whole point. if it doesn't get saved, future init is gonna be standing there like "girl what did we even decide" 💀

⭐ RETURN ⭐

  • zero when the save was successful 🎉 slay, it worked
  • negative values otherwise 🙈 aka something went sideways
