rx_alloc_skb(9)

💖 rx_alloc_skb(9) 💖

okay so bestie, welcome to the Kernel API Manual — this one's a lil page from the kernel docs, section 9, and it's literally about one function: rx_alloc_skb. buckle up, it's a short one but she's iconic 🎀

---

✨ NAME ✨

rx_alloc_skb — allocate skb and map it to dma address 🦋

like, that's the whole vibe. it grabs you an skb and then maps it to a dma address. slay.

---

🌸 SYNOPSIS 🌸

struct sk_buff * rx_alloc_skb (struct hinic_rxq *rxq , dma_addr_t
*dma_addr );

that's the signature, copy it exactly, no cap — struct sk_buff * return type, two args, and yes there's a space before the comma in the original so we're keeping it, we don't fix things here 💅

---

🎀 ARGUMENTS 🎀

• rxq — the rx queue. that's her. the receive queue in question 🧚
• dma_addr — the returned dma address for the skb. so this is an out-param situation, the function fills it in and hands it back to you 🫶

---

💜 DESCRIPTION 💜

Return skb.

that's it. that's the description. short queen energy 👑 ngl the manpage is not exactly verbose here — it returns the skb, that's the whole documented behaviour, and we are not inventing more lore than the page gives us 🙈
