igc_add_rx_frag(9)

💅 igc_add_rx_frag — a Kernel API Manual moment ✨

okay so bestie, welcome to the Kernel API Manual 🎀 this one's about igc_add_rx_frag(9), and honestly it's giving "small function, big job" energy. no cap, it's a whole vibe.

---

🌸 NAME 🌸

igc_add_rx_frag — Add contents of Rx buffer to sk_buff 💖 that's literally the whole personality.

---

⭐ SYNOPSIS ⭐

void igc_add_rx_frag (struct igc_ring *rx_ring , struct igc_rx_buffer
*rx_buffer , struct sk_buff *skb , unsigned int size );

look at her 🫶 returns void, takes four things, gets straight to business. iconic behaviour honestly.

---

🦋 ARGUMENTS 🦋

• rx_ring — the rx descriptor ring you're transacting packets on 🌀 like, this is the ring the packets live on, ok?
• rx_buffer — the buffer containing the page to add 📄 she's the one holding the goods.
• skb — the sk_buff you're placing the data into 🧺 the basket, basically. the destination.
• size — size of the buffer to be added 📏 how much of it we're moving. no more, no less.

---

💜 DESCRIPTION 💜

so here's the tea ☕ this function will add the data contained in rx_buffer->page to the skb. that's it. that's the function. she takes the page living inside rx_buffer and slides that data right into the skb. lowkey simple, highkey essential ✨

💀 quick reminder bestie: the args are struct igc_ring *, struct igc_rx_buffer *, struct sk_buff *, and unsigned int. type-safe queen. slay. 💅
