i40e_create_tx_ctx(9)

📦 version 7.3.1, in nixpkgs unstable

💅 i40e_create_tx_ctx — the Kernel API Manual, but make it cute 🎀

okay so bestie, this is a page from the Kernel API Manual (that's the manual name, we're not copying the header line twice, iykyk ✨), and it's all about one little function that builds a Tx context descriptor. yes it sounds nerdy. no you're not gonna be bored. let's go 💖

✨ NAME ✨

i40e_create_tx_ctx — literally the function that builds the Tx context descriptor. that's it. that's the vibe 🌸

🦋 SYNOPSIS 🦋

void i40e_create_tx_ctx (struct i40e_ring *tx_ring , const u64
cd_type_cmd_tso_mss , const u32 cd_tunneling , const u32 cd_l2tag2 );

no cap, it returns nothing (void) — it just does its little descriptor-building thing and dips 💅

👑 ARGUMENTS 👑

four things, and every single one matters, bestie. not me listing them all 🫶

  • tx_ring — the ring you're creating the descriptor on. like, this is the main character of the argument list tbh 🌀
  • cd_type_cmd_tso_mss — Quad Word 1 ✨ (yes that's really what the manpage says, i'm not making this up)
  • cd_tunneling — Quad Word 0 - bits 0-31. the low half. the little spoon 🥺
  • cd_l2tag2 — Quad Word 0 - bits 32-63. the high half. the big spoon. iconic pair honestly 💕

🌈 SEE ALSO 🌈

okay this is the part where I flex 😤 the whole squad — plus the kernel file it lives in — is right here, and no I did not skip a single one:

like… that's the whole friend group 💀 and yes, the two with double underscores are exactly as written, don't @ me.

ngl bestie, this is the whole page. every argument, every quad word, every single SEE ALSO. you ate that. periodt 💅🔥

okay bye, sending you off with the receipts 🧚: this one lives in ./drivers/net/ethernet/intel/i40e, dated October 2026, and it's i40e_create_tx_ctx(9) — go be a main character in the kernel, ily 🎀💜
