igc_cleanup_headers(9)

📦 version 7.3.1, in nixpkgs unstable

💖 NAME 💖

igc_cleanup_headers — the function that swoops in and corrects corrupted or empty headers 💅

✨ SYNOPSIS ✨

bool igc_cleanup_headers (struct igc_ring *rx_ring , union
igc_adv_rx_desc *rx_desc , struct sk_buff *skb );

🎀 ARGUMENTS 🎀

  • rx_ring — the rx descriptor ring that the packet is being transacted on. like, the whole operation is happening on this ring, ok?
  • rx_desc — a pointer to the EOP Rx descriptor 🫶
  • skb — a pointer to the current skb that's getting fixed up

🦋 DESCRIPTION 🦋

okay so picture this: you're pulling data in on pages only, which means there is literally no data present in the skb header. this function handles exactly that case 💀

and then, on top of that — if skb isn't at least 60 bytes, we gotta pad it so it's large enough to qualify as a valid Ethernet frame. no cap, 60 bytes is the vibe minimum 🎀

Returns true if an error was encountered and skb was freed. so if it comes back true, the skb is gone-gone, bestie 😭
