ice_hash_moveback(9)

💖 NAME 💖

okay so bestie, this is ice_hash_moveback(9) from the Kernel API Manual, and its whole main-character job is literally to add an RSS hash configuration for a VF. No cap. 💅✨

✨ SYNOPSIS ✨

copy this signature exactly, iykyk — it’s giving “don’t touch the spacing” energy:

int ice_hash_moveback (struct ice_vf *vf , struct ice_rss_hash_cfg *cfg
);

🎀 ARGUMENTS 🎀

• vf — VF pointer. That’s the pointer bestie 🫶
• cfg — RSS hash configuration to apply. This is the config we’re serving ✨

🦋 DESCRIPTION 🦋

okay so the actual vibe: add cfg to vf if the context is valid and the VSI exists; then it programs the HW. That’s the whole function. Periodt. 💖

🌸 RETURN 🌸

• 0 — on success. Slay, it worked 💅
• -ENOENT — if cfg is invalid or VSI is missing. no cfg/no VSI, no entry, sad girl hours 😭
• -EBUSY — if hardware programming fails. HW programming said busy-vibes, so that’s the error 💀
