stmmac_xmit(9) — Kernel API Manual 💅

✨ NAME ✨

stmmac_xmit — Tx entry point of the driver. okay so bestie, this is the stmmac_xmit(9) page from the Kernel API Manual, and we are literally about to get into the Tx of it all. no cap 🦋

✨ SYNOPSIS ✨

netdev_tx_t stmmac_xmit (struct sk_buff *skb , struct net_device *dev );

✨ ARGUMENTS ✨

• skb — the socket buffer 🧺
• dev — device pointer 🫵

✨ DESCRIPTION ✨

okay so this is the tx entry point of the driver, periodt. It programs the chain or the ring and supports oversized frames and SG feature. that's the whole flex, bestie — chain-or-ring programming, oversized frames, and SG, all up in here 💅✨

✨ SEE ALSO ✨
