💖 ice_del_fdir_ethtool(9) — the "bye-bye, Flow Director filter" era 💖

okay so bestie, welcome to the Kernel API Manual ✨ this little cutie lives in the kernel API pages, and its whole personality is: delete a Flow Director filter. That's it. That's the vibe. 🎀

✨ NAME ✨

ice_del_fdir_ethtool — delete Flow Director filter 🗑️💅

---

🌸 SYNOPSIS 🌸

int ice_del_fdir_ethtool (struct ice_vsi *vsi , struct ethtool_rxnfc
*cmd );

---

🦋 ARGUMENTS 🦋

• vsi — pointer to target VSI 👑 (yes, the target one, main character energy)
• cmd — command to add or delete Flow Director filter 📝 (she's the one holding the instructions, iykyk)

💜 DESCRIPTION 💜

Returns 0 on success and negative values for failure. that's the whole story fr fr 😭 — zero means slay, negative means it's giving struggle. no cap, that's literally it. 💀
