zd_mac_tx_status(9)

💅 zd_mac_tx_status — Kernel API Manual, bestie edition

okay so this is zd_mac_tx_status(9) from the Kernel API Manual, and it's literally the little function that goes "hey, does anybody want to know how this packet did?" 🦋

---

✨ NAME ✨

zd_mac_tx_status — reports tx status of a packet if required

like, if required. that "if" is doing so much work here, keep an eye on it 👀

---

🎀 SYNOPSIS 🎀

void zd_mac_tx_status (struct ieee80211_hw *hw , struct sk_buff *skb ,
int ackssi , struct tx_status *tx_status );

she takes four things and returns absolutely nothing (void, queen of not giving anything back 💅)

---

🌸 ARGUMENTS 🌸

• hw — a struct ieee80211_hw pointer. yes bestie, a pointer to the hardware struct, we love a pointer ✨
• skb — a sk-buffer 🫶
• ackssi — ACK signal strength 📶
• tx_status — success and/or retry. that's it, that's the whole vibe 🔥

---

💖 DESCRIPTION 💖

okay so here's what's actually going down: this information calls ieee80211_tx_status_irqsafe if required by the control information. that's a conditional, bestie, don't forget the conditional 😭

it also copies the control information into the status information. yes, literally copies it over. no cap. 🧚

and then — plot twist — if no status information has been requested, the skb is freed. so if nobody asked, the buffer gets yeeted into the void. that's just how it is 🙈

ngl, that free is the main character of this paragraph. if no status was requested, the skb is gone. periodt. 💀
