ixgbe_fso(9)

💅 ixgbe_fso — the Kernel API Manual page, bestie edition 🎀

okay so this is ixgbe_fso(9), straight out of the Kernel API Manual, and it's literally the page about ixgbe FCoE Sequence Offload (FSO). yes the acronym is FSO. yes we're gonna say it a lot. no cap. ✨

---

🌸 NAME 🌸

ixgbe_fso — the ixgbe FCoE Sequence Offload situation, aka FSO. iconic behavior only. 💖

---

✨ SYNOPSIS ✨

int ixgbe_fso (struct ixgbe_ring *tx_ring , struct ixgbe_tx_buffer
*first , u8 *hdr_len );

that's the whole vibe: returns an int, takes three args. copy it exactly, don't be weird about it. 🫶

---

🦋 ARGUMENTS 🦋

• tx_ring — the tx desc ring. that's the descriptor ring, your main character of a data structure. 👑
• first — the first tx_buffer structure, and bestie it's carrying skb, tx_flags, and protocol in there. it's giving "everything bagel" fr fr. 🥯
• hdr_len — the hdr_len that gets returned. it's a u8 *, so yes, we're writing through a pointer. slay. 💅

---

🧚 DESCRIPTION 🧚

so what does it actually do? it sets up large send offload for FCoE. that's it. that's the whole glow-up. large. send. offload. for. FCoE. periodt. 🔥

---

⭐ RETURN ⭐

• 0 means success — ate and left no crumbs 💖
• < 0 means error — not the vibe, we don't stan 😭

lowkey important: it's 0 for success, < 0 for error. not 1, not -1 specifically, just < 0. don't come for me, that's what the page says. 💀
