ice_sync_fltr_subtask(9)

💅 ice_sync_fltr_subtask(9) — the Kernel API Manual, but make it make sense

okay so bestie, welcome to the glow-up era of the kernel API manual ✨ this one's a <pink>page 9</pink> situation, meaning it's a kernel function, and it's genuinely tiny. like, one-function-one-job tiny. and honestly? we love a focused queen. 👑

🌸 NAME 🌸

ice_sync_fltr_subtask — Sync the VSI filter list with HW

no cap, that's the whole assignment. it takes the VSI filter list and it syncs it up with the hardware. that's the vibe. that's the job. 💅

---

✨ SYNOPSIS ✨

void ice_sync_fltr_subtask (struct ice_pf *pf );

it returns void, so don't be out here expecting a little treat back. it does the thing and it leaves. main character energy fr fr 🦋

---

🎀 ARGUMENTS 🎀

• pf — the board private structure. that's it, that's the one (1) argument. she keeps her circle small and her structs private. 🙈

heads up bestie: there's literally just the one parameter, so if you were bracing for a long list — breathe. you're safe. 😭
