iavf_add_fdir_ethtool(9)

✨ iavf_add_fdir_ethtool(9) ✨

okay so bestie, welcome to the iavf_add_fdir_ethtool(9) era of the Kernel API Manual 💅 this one's a little cutie from the iavf corner of the kernel — the Intel VF driver gang 🦋 she's short, she's sweet, she adds a Flow Director filter, and she tells you exactly how it went. let's get into it 💖

---

🌸 NAME 🌸

iavf_add_fdir_ethtool — add Flow Director filter ✨

like, literally the function's whole personality is adding a Flow Director filter. that's the vibe check and she passes 👑

---

🎀 SYNOPSIS 🎀

int iavf_add_fdir_ethtool (struct iavf_adapter *adapter , struct
       ethtool_rxnfc *cmd );

so she takes two things and hands you back an int. that's the whole shape of her, no cap 🫶

---

🦋 ARGUMENTS 🦋

• adapter — pointer to the VF adapter structure. that's your VF's main character data structure, she's holding the whole adapter situation 💜
• cmd — command to add Flow Director filter. fr fr, this is the actual "add this filter pls" instruction 🎯

---

🔥 DESCRIPTION 🔥

Returns 0 on success and negative values for failure 💀

that's it. that's the description. she's not a long-story girlie, she's a results girlie. zero means slay, negative means something went sideways — and ngl, the manpage is not about to elaborate on which negative values or why, so neither am I 🙈

and that's the page!! mwah 💋

little sign-off for the girlies who read to the bottom: this one's straight out of the ./drivers/net/ethernet/intel/iavf directory, dated October 2026, and it belongs to the iavf_add_fdir_ethtool(9) manual page 🫶✨ go add some Flow Director filters bestie, you got this 💖🌸
