fm10k_cleanup_headers(9)

💖 fm10k_cleanup_headers(9) 💖

okay so bestie, we're in the Kernel API Manual today and this one is genuinely a little fixer-upper function, no cap ✨

---

✨ NAME ✨

fm10k_cleanup_headers — literally just here to correct corrupted or empty headers 🎀

---

🦋 SYNOPSIS 🦋

bool fm10k_cleanup_headers (struct fm10k_ring *rx_ring , union
fm10k_rx_desc *rx_desc , struct sk_buff *skb );

like she takes three things and gives you back a bool, periodt 💅

---

🌸 ARGUMENTS 🌸

• rx_ring — the rx descriptor ring that the packet is being transacted on. that's her home turf 🏠
• rx_desc — pointer to the EOP Rx descriptor. yes EOP, ikyk 👀
• skb — pointer to the current skb that's being fixed. glow-up in progress 🧚

---

💜 DESCRIPTION 💜

so the whole vibe here is: we're pulling data in on pages only, which means there's literally no data present in the skb header 😭 she's addressing exactly that case. empty header? corrupted header? handled.

and then — bonus round — if the skb is not at least 60 bytes, we need to pad it so it's large enough to qualify as a valid Ethernet frame. like yes, she needs to be at least 60 bytes to be taken seriously as an Ethernet frame, that's just the rules 📏✨

Returns true if an error was encountered and skb was freed. so true is the bad ending bestie, don't get it twisted 💀
