💅 i40e_update_ethtool_fdir_entry — Kernel API Manual ✨

okay so bestie, welcome to the i40e_update_...l_fdir_entry(9) page — yes the header is literally abbreviated like that, no I don't know why, it's giving "ran out of characters" energy 😭. Anyway, this is a Kernel API Manual entry and it's all about keeping your Flow Director filter list cute and correct. Let's go 🫶

🌸 NAME 🌸

i40e_update_ethtool_fdir_entry — updates the fdir filter entry

Like, it updates the fdir filter entry. That's the whole vibe. Periodt.

---

✨ SYNOPSIS ✨

int i40e_update_ethtool_fdir_entry (struct i40e_vsi *vsi , struct
i40e_fdir_filter *input , u16 sw_idx , struct ethtool_rxnfc *cmd );

---

🎀 ARGUMENTS 🎀

• vsi — Pointer to the targeted VSI. This is the main character of the operation, the VSI we're aiming at 💖
• input — The filter to update, or NULL to indicate deletion. Yep, NULL here means "bestie we're deleting", so handle with intent 🙈
• sw_idx — Software index to the filter. It's the index, but like, in software 🔢
• cmd — The command to get or set Rx flow classification rules 👑

---

🦋 DESCRIPTION 🦋

So what does it actually do? It updates (or deletes) a Flow Director entry from the hlist of the corresponding PF. That's it, that's the whole job — but it does it so well, lowkey iconic 💅

Returns 0 on success ⭐
