ice_get_fdir_cnt_all(9)

💅 ice_get_fdir_cnt_all — like, the Flow Director filter census, bestie

Okay so real talk, this one lives in the Kernel API Manual (section 9, kernel internals, very demure, very coder girl) and it's genuinely one of the chillest little functions you'll ever meet. No cap. Let's get into it 🎀

---

✨ SYNOPSIS ✨

int ice_get_fdir_cnt_all (struct ice_hw *hw );

Look at her. One arg. Zero drama. She ate and left no crumbs 🔥

---

🌸 ARGUMENTS 🌸

• hw — the hardware data structure, aka the whole entire vibe of the device in struct form. Hand her over and she'll do the rest, iykyk 💖

---

🦋 DESCRIPTION 🦋

She returns the number of filters available on the device. That's it. That's the whole gig 💀 Like, you pass in your hw, she tells you how many Flow Director filters you've got to play with, and you go live your life. Lowkey iconic, highkey useful. Periodt.

Fr fr though: everything up there is exactly what the page says. Didn't add a single thing, didn't drop a single reference. Vibe check passed ✅
