🦋 i40e_rx_checksum(9) 🦋

okay so bestie, welcome to the i40e_rx_checksum(9) page from the Kernel API Manual 💖. this one is short and it's literally all about one glow-up move: if the hardware indicated a good cksum, the function indicates that in the skb. no cap, that's the whole vibe. ✨

✨ NAME ✨

i40e_rx_checksum — indicate in skb if hw indicated a good cksum 💅

🌸 SYNOPSIS 🌸

here's the signature, iconic:

void i40e_rx_checksum (struct i40e_vsi *vsi , struct sk_buff *skb ,
       union i40e_rx_desc *rx_desc );

🎀 ARGUMENTS 🎀

• vsi — the VSI we care about 💜
• skb — the skb currently being received and modified 🦋
• rx_desc — the receive descriptor 🎀
