💅 ice_xdp_xmit — the manual page bestie

okay so this is ice_xdp_xmit, and yes it lives in the Kernel API Manual (section 9, driver land, we love her) ✨ she's the one who actually sends your packets out to the XDP ring for transmission. main character energy tbh 👑

🌸 NAME 🌸

ice_xdp_xmit — submit packets to XDP ring for transmission 🦋

✨ SYNOPSIS ✨

int ice_xdp_xmit (struct net_device *dev , int n , struct xdp_frame
**frames , u32 flags );

🎀 ARGUMENTS 🎀

  • dev — the netdev, aka the network device we're doing all this for 🫶
  • n — how many XDP frames we're trying to transmit. like, the count, the headcount, the n 💅
  • frames — the actual XDP frames being transmitted. this is the cargo, bestie 📦
  • flags — the transmit flags 🌈

💖 DESCRIPTION 💖

So like — this returns the number of frames successfully sent. slay ✨

Failed frames get free'ed by the XDP core, so you don't gotta worry about those 💀🙈

⚠️ but listen: for error cases, a negative errno code is returned, and no frames are transmitted. which means the caller must handle freeing frames themselves. no cap, that's on you 😭
