rt2x00queue_map_txskb(9)

💖 rt2x00queue_map_txskb(9) — from the Kernel API Manual ✨

okay bestie, gather round, because this is genuinely one of the little worker functions that keeps your Wi-Fi from absolutely falling apart 🫶 it lives in the kernel API manual and it's got main character energy in the most lowkey way possible.

---

🌸 NAME 🌸

rt2x00queue_map_txskb — maps a skb into DMA so it can go out for TX purposes 💅

---

✨ SYNOPSIS ✨

int rt2x00queue_map_txskb (struct queue_entry *entry );

---

🎀 ARGUMENTS 🎀

• entry — a pointer to struct queue_entry 👑 that's it, that's the whole argument list, she's low maintenance

---

💅 DESCRIPTION 💅

so here's the tea ☕: this function returns -ENOMEM if the mapping fails, and 0 otherwise. that's literally it, no cap. mapping fail = you get -ENOMEM back, mapping good = you get 0. iconic behavior honestly 🦋

ngl, if you see that -ENOMEM come back, the map didn't happen — that's your vibe check failing in the most literal sense 😭
