send_packet(9)

💌 send_packet(9) — okay bestie, let's talk packets

okay so this is the send_packet(9) page from the Kernel API Manual, and it's lowkey iconic because it's short, sweet, and does exactly what it says. no cap. 🫶

✨ NAME

send_packet — send packet. that's the name, that's the vibe, that's the whole assignment. 💅

🎀 SYNOPSIS

void send_packet (struct sk_buff *skb , struct net_device *dev );

🦋 ARGUMENTS

• skb — Socket buffer. the socket buffer, aka the packet's little carrying case.
• dev — Network device. the network device, aka where this packet is headed.

🔥 DESCRIPTION

okay so the description is literally: this routine is used to send a packet out to the network. that's it. that's the whole plot. send packet, out to the network, done. no extra lore, no secret side quest. 🫶

cute sign-off: this page lives at source/version ./drivers/net/ethernet/micrel, it's dated October 2026, and it's still send_packet(9). periodt. 💅✨
