t4vf_fw_reset(9)

💅 t4vf_fw_reset — bestie, we're resetting the firmware

okay so this is t4vf_fw_reset(9), straight out of the Kernel API Manual ✨ and it's genuinely one of the shorter ones so stay with me 🫶

---

✨ SYNOPSIS ✨

int t4vf_fw_reset(struct adapter *adapter);

like, that's it. that's the whole signature. iconic behavior honestly 👑

---

🎀 ARGUMENTS 🎀

• adapter — the adapter 💖 yeah that's the whole description. it's giving "left as an exercise to the reader" but for real, it's just the adapter.

---

🌸 DESCRIPTION 🌸

So what it does: it issues a reset command to FW 🔥 (that's firmware, iykyk).

now here's the part that actually matters, so pay attention bestie:

• For a Physical Function, this would result in the Firmware resetting all of its state 💀 like, all of it. everything. gone. main character firmware wipe.
• For a Virtual Function, this just resets the state associated with the VF — so it's contained, no cap, your VF's own little world gets reset and nothing else 🦋

lowkey important distinction, so don't go thinking a VF reset nukes everything, because it does not. periodt.
