iavf_add_fdir_filter(9)

💖 iavf_add_fdir_filter(9) — the Kernel API Manual glow-up 💖

okay bestie, so this is a page straight out of the Kernel API Manual, and it's all about iavf_add_fdir_filter — yes, the (9) is right there in the name, that's the section, we love a consistent queen ✨

---

🌸 NAME 🌸

iavf_add_fdir_filter — and ngl, the original page literally leaves the description blank after that dash 🙈 so like… the name is the name, that's what we got, and honestly the rest of the page picks up the slack fr fr.

---

🦋 SYNOPSIS 🦋

void iavf_add_fdir_filter (struct iavf_adapter *adapter );

it returns void, bestie — nothing comes back out, it just does the thing 💅

---

🎀 ARGUMENTS 🎀

• adapter — the VF adapter structure. that's the whole vibe, it's the thing you hand over so the function knows which adapter we're talking about 🫶

---

⭐ DESCRIPTION ⭐

so here's the tea: this function requests that the PF add Flow Director filters — and those filters are the ones specified by the user via ethtool. that's it, that's the whole description, no cap 😭

like, the VF is politely asking the PF to please go ahead and install those Flow Director filters the user set up through ethtool. main character energy from the PF, honestly 👑
