iavf_get_ethtool_fdir_entry(9)

💅 iavf_get_ethtool_fdir_entry — the manual page, but make it make sense

okay so before we even start: this is iavf_get_ethtool_fdir_entry(9), straight out of the Kernel API Manual, and bestie… she's a short one, but she eats. ✨

---

🌸 NAME 🌸

iavf_get_ethtool_fdir_entry — fills the ethtool structure with Flow Director filter data 💖

like. that's the whole job. that's her whole personality. and honestly? iconic.

---

🦋 SYNOPSIS 🦋

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

yes the line break in the middle of the parameter list is real, that's not me being chaotic, that's just how the page is laid out 🫶. copy it exactly, no cap.

---

🎀 ARGUMENTS 🎀

• adapter — the VF adapter structure that contains the filter list. like okay so this is where all the filter deets are living, she's the one holding the list, main character energy tbh 👑
• cmd — the ethtool command data structure that receives the filter data. lowkey she's just here to be filled up with the good stuff 🍓

---

✨ DESCRIPTION ✨

Returns 0 as expected for success by ethtool. that's it. that's the description. she's a one-liner and she knows it 💅

ngl this is the shortest DESCRIPTION section I've ever seen and I respect it SO much — no waffling, no yapping, just vibes and a return value 🙈
