fnic_flush_tx(9)

💅 fnic_flush_tx(9) — bestie's guide to flushing them frames ✨

okay so this is a page from the Kernel API Manual, and it's all about fnic_flush_tx, which honestly is giving "small function, big responsibility" energy. no cap. 🫶

---

✨ NAME ✨

fnic_flush_tx — send queued frames. that's it, that's the whole vibe. 🎀

---

🌸 SYNOPSIS 🌸

void fnic_flush_tx (struct work_struct *work );

literally the entire signature. it returns void, so don't go looking for a return value, bestie, there isn't one. 💀

---

🦋 ARGUMENTS 🦋

• work — pointer to work element. that's the whole job, she just points at the work element and off we go ✨

---

👑 DESCRIPTION 👑

okay so picture this: frames are sitting around waiting to go out, and this function is the one that finally sends them. specifically, she sends frames that were waiting to go out in FC or Ethernet mode. 🔥

and here's the important bit — whenever we're changing modes we purge queued frames, so these frames should be queued for the stable mode that we're in, either FC or Ethernet. iykyk. no chaotic mode-hopping frames allowed. 🙈

one little caveat to keep in your notes: this whole thing is called without fnic_lock held. that's not a suggestion, that's the deal. 💅
