t4vf_eth_xmit(9)

🌸 NAME 🌸

t4vf_eth_xmit — add a packet to an Ethernet TX queue. This page is from the Kernel API Manual, and yes bestie, the manual name is t4vf_eth_xmit(9) — iconic behavior only 💅.

---

✨ SYNOPSIS ✨

netdev_tx_t t4vf_eth_xmit (struct sk_buff *skb , struct net_device *dev
);

---

🎀 ARGUMENTS 🎀

• skb — the packet 💌 (that's the whole assignment, no cap)
• dev — the egress net device 🌐

---

💅 DESCRIPTION 💅

Okay so this is the moment where a packet gets added to an SGE Ethernet TX queue. It's giving transmit-queue main character energy 🌈.

⚠️ Heads up, bestie: it runs with softirqs disabled. That's not a drill — that's literally the context it runs in.
