igb_cleanup_headers(9)

okay bestie, welcome to igb_cleanup_headers(9) from the Kernel API Manual — it’s giving “tiny bool helper with big header-energy” and honestly we’re obsessed 💅✨

🌸 NAME 🌸

igb_cleanup_headers — Correct corrupted or empty headers 🫶

🦋 SYNOPSIS 🦋

here’s the whole signature, verbatim, no cap:

bool igb_cleanup_headers (struct igb_ring *rx_ring , union
e1000_adv_rx_desc *rx_desc , struct sk_buff *skb );

🎀 ARGUMENTS 🎀

• rx_ring — rx descriptor ring packet is being transacted on 💖
• rx_desc — pointer to the EOP Rx descriptor ✨
• skb — pointer to current skb being fixed 😭

💜 DESCRIPTION 💜

okay so here’s the situation: this function addresses the case where we’re pulling data in on pages only and as such no data is present in the skb header. it’s literally “empty header era,” and the function is here to deal with it 🌸

in addition, if skb is not at least 60 bytes, we need to pad it so that it is large enough to qualify as a valid Ethernet frame. the way that 60-byte minimum is non-negotiable — periodt 💅

returns true if an error was encountered and skb was freed. that’s the return vibe, bestie 🫶
