🦋 i40e_features_check(9) — Kernel API Manual 🦋

okay so bestie, we're in the Kernel API Manual today, and this page is literally about i40e_features_check. Yes, it's a big-girl Intel driver function. Yes, it's short. No, I'm not skipping anything. Let's go 💅

✨ NAME ✨

i40e_features_check — literally here to validate encapsulated packet conforms to limits. That's the whole vibe check of this function. It looks at a packet and goes "hm, does this actually fit inside what we can do?" and that's it, that's the function 🫶

🌸 SYNOPSIS 🌸

netdev_features_t i40e_features_check (struct sk_buff *skb , struct
net_device *dev , netdev_features_t features );

She returns a netdev_features_t and she takes three things. Not me being obsessed with a return type but like... iconic 💖

💖 ARGUMENTS 💖

  • skb — the skb buff 🎀 yes that's the entire description, we love a minimalist king
  • dev — This physical port's netdev, aka the net device belonging to this physical port
  • features — the offload features that the stack believes apply 🔥 key word being believes, this function is the one doing the checking
