💖 i40e_construct_skb(9) — the Kernel API Manual glow-up 💖

okay so bestie, welcome to the Kernel API Manual, page i40e_construct_skb(9). this is a networking girlie function, she lives in the Intel i40e driver, and she's about to hand you a whole brand-new sk_buff like it's a gift bag at a party 🎀

✨ SYNOPSIS ✨

struct sk_buff * i40e_construct_skb (struct i40e_ring *rx_ring , struct
xdp_buff *xdp );

like, yes, that's the whole signature. she takes two args and gives you back a struct sk_buff *. no cap 💅

🫶 ARGUMENTS 🫶

  • rx_ring — the rx descriptor ring where the packet transactions happen. this is the literal venue of the whole operation, the main character ring 🔥
  • xdp — an xdp_buff that points at the data. she's the vibe check on where the bytes actually live 💜

🌸 DESCRIPTION 🌸

so what she does is: she allocates an skb. a fresh one. brand new. ✨

and then — and this is the fun part — she populates it with the page data from the current receive descriptor. taking care to set up the skb correctly, because bestie, if you do not set up your skb correctly the whole thing is giving chaos 😭 she is very careful about this. she does it right. periodt.

👑 SEE ALSO 👑

the kernel file for this is ./drivers/net/ethernet/intel/i40e/i40e_txrx.c — that's where she lives, that's her address 🏡

and now, the friend group 💖 (they're all (9) pages, they all run together, it's literally a whole squad):
