# 💅 i40e_lan_xmit_frame(9)

okay so bestie, welcome to the i40e_lan_xmit_frame page — it lives in section 9 of the Kernel API Manual, and honestly? it's a short one, so we can absolutely devour it together 🫶

---

🌸 NAME 🌸

i40e_lan_xmit_frame — picks the right VSI and Tx queue so your buffer actually gets sent ✨

Like, it's the little matchmaker of the transmit path: it looks at your buffer, figures out which virtual station interface and which Tx queue it belongs to, and sends it on its way. no cap 💅

🦋 SYNOPSIS 🦋

netdev_tx_t i40e_lan_xmit_frame (struct sk_buff *skb , struct net_device
*netdev );

🎀 ARGUMENTS 🎀

• skb — the send buffer 💌 (the thing you're trying to get out the door)
• netdev — the network interface device structure 🖧 (the whole device vibe it's attached to)

⭐ DESCRIPTION ⭐

So the function returns NETDEV_TX_OK if it got sent — slay, we love a success — and if not? an error code. that's it, that's the whole description. short king energy 👑

ngl the manpage does not elaborate beyond that, so I'm not gonna invent lore for you — what it says is what it does: NETDEV_TX_OK on send, otherwise an error code. 🍓
