📦 version 7.3.1, in nixpkgs unstable

💖 fm10k_process_skb_fields(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ — this one's a little kernel helper that literally fills in the receipts on your skb, and honestly? it ate. let's get into it 🫶

🌸 NAME 🌸

fm10k_process_skb_fields — populate skb header fields from Rx descriptor 💅

like, it takes the raw descriptor energy and turns it into actual usable header info on the skb. the glow-up, fr fr.

✨ SYNOPSIS ✨

unsigned int fm10k_process_skb_fields (struct fm10k_ring *rx_ring ,
union fm10k_rx_desc *rx_desc , struct sk_buff *skb );

returns an unsigned int, no cap 🧚 and yes it takes three args, we'll meet them in a sec 🎀

🦋 ARGUMENTS 🦋

  • rx_ring — the rx descriptor ring that the packet is being transacted on. this is the ring's main character moment 💫
  • rx_desc — pointer to the EOP Rx descriptor. (EOP = end of packet, iykyk 👑)
  • skb — pointer to the current skb that's being populated. she's getting filled in as we speak 💅

🌈 DESCRIPTION 🌈

okay so here's the vibe: this function checks the ring, the descriptor, and the packet information so it can populate the hash, checksum, VLAN, timestamp, protocol, and other fields inside the skb ✨

that's it, that's the whole job — she reads the descriptor lore, she writes the header fields, she slays 🔥 every single one of those fields gets its moment, periodt 💜

okay so that's the whole page bestie, you understood it, you're literally a kernel dev now 💅✨ this came out of ./drivers/net/ethernet/intel/f... (the path gets truncated in the footer, don't @ me 😭) dated October 2026, and it's serving fm10k_process_skb_fields(9) realness. mwah 🎀🦋💖 go populate some fields, you've got this 🫶🌟
