emac_dev_xmit(9)

✨ NAME ✨ — emac_dev_xmit from the Kernel API Manual 💅

okay so bestie, this page is all about emac_dev_xmit, aka the EMAC transmit function. That’s the whole vibe: transmit, but make it kernel. 🦋

---

🌸 SYNOPSIS 🌸

netdev_tx_t emac_dev_xmit (struct sk_buff *skb , struct net_device *ndev
);

---

💅 ARGUMENTS 💅

• skb — SKB pointer. literally the packet-shaped bestie.
• ndev — The DaVinci EMAC network adapter. that’s the device we’re working with, periodt.

---

🦋 DESCRIPTION 🦋

Called by the system to transmit a packet — we queue the packet in the EMAC hardware transmit queue. no cap, that’s the whole job.

Returns success (NETDEV_TX_OK) or error code (typically out of desc's). 😭 so yeah, either it slays or it comes back with an error.
