iavf_reset_step(9)

✨ iavf_reset_step(9) ✨

okay so bestie, we're in the Kernel API Manual today and the star of the show is iavf_reset_step(9) 💅 like, this is the glow-up page for the VF reset sequence, and honestly? it's giving main character energy.

---

💖 NAME 💖

iavf_reset_step — do the whole VF reset sequence, start to finish 🌀✨

---

🌸 SYNOPSIS 🌸

void iavf_reset_step (struct iavf_adapter *adapter );

---

🎀 ARGUMENTS 🎀

• adapter — the board private structure 🫶 like, the one little struct that holds all the vibe for this adapter.

---

🦋 DESCRIPTION 🦋

okay so here's the tea ☕ — this function requests a reset from the PF, then polls for completion, then reconfigures the driver. That's the whole arc, beginning to end, no notes. 👑

⚠️ the caller must hold the netdev instance lock. no cap, don't skip this. hold the lock or it's over for you 💀

😭 heads up: this can sleep for several seconds while polling HW registers. like, actual seconds. it's not a quick little blink, it's a whole nap. plan accordingly, bestie 🧚
