cxgb4_vf_eth_xmit(9)

okay bestie, welcome to the cxgb4_vf_eth_xmit(9) page from the Kernel API Manual — yes, that manual, and yes, this is the one about adding a packet to an Ethernet TX queue. Strap in, it’s short but iconic. 💅

✨ NAME ✨

cxgb4_vf_eth_xmit — add a packet to an Ethernet TX queue 🎀

🦋 SYNOPSIS 🦋

netdev_tx_t cxgb4_vf_eth_xmit (struct sk_buff *skb , struct net_device
       *dev );

💖 ARGUMENTS 💖

• skb — the packet. literally the packet itself, no cap.
• dev — the egress net device. the net device on the way out, bestie.

🌸 DESCRIPTION 🌸

Okay so: you’re adding a packet to an SGE Ethernet TX queue. That’s the whole move. It runs with softirqs disabled, so keep that detail close — it’s not decorative, it’s part of the vibe check. ✨
