💅 nfp_nfd3_rx_give_one 💅

okay so this is a page straight outta the Kernel API Manual, and bestie, it's a short one but it's lowkey important. sit down, grab a strawberry 🍓, and let's get into it.

✨ NAME ✨

nfp_nfd3_rx_give_one — the little function that puts a mapped skb onto the software ring and the hardware ring. both. at once. she's multitasking, she's doing the most, and honestly? iconic. 👑

🦋 SYNOPSIS 🦋

void nfp_nfd3_rx_give_one (const struct nfp_net_dp *dp , struct
       nfp_net_rx_ring *rx_ring , void *frag , dma_addr_t dma_addr );

no return value, she just does it and leaves. main character energy fr fr. 💅

🎀 ARGUMENTS 🎀

• dp — the NFP Net data path struct. that's the vibe-setter, the context, the whole situation.
• rx_ring — the RX ring structure. this is the ring she's about to be handed to. 🦋
• frag — the page fragment buffer. it's a void *, so it's mysterious, it's undefined, it's everything.
• dma_addr — the DMA address of the skb mapping. the ✨address✨. the way she knows where stuff lives.

ngl bestie, that's literally all four of them. no defaults, no optional extras, no hidden flags. you pass all four or you don't pass at all. 😭
