STRUCT IDPF_TX_OFFLOAD_PARAMS(9)

✨ struct idpf_tx_offload_params — NAME ✨

okay so bestie, welcome to the Kernel API Manual 💅 this little page is all about struct idpf_tx_offload_params — literally the offload parameters for a given packet 🎀

it's giving "one struct to rule every packet's offload vibes" and honestly? obsessed. ✨

---

🌸 SYNOPSIS 🌸

struct idpf_tx_offload_params {
    u32 tx_flags;
    u32 hdr_offsets;
    u32 cd_tunneling;
    u32 tso_len;
    u16 mss;
    u16 tso_segs;
    u16 tso_hdr_len;
    u16 td_cmd;
 };

no cap, that's the whole vibe right there 👑 copy it exactly if you're typing it out, bestie, don't be out here "fixing" the spacing 🫶

---

💖 Members 💖

like a group chat but make it a struct — every member has a role and every role slays:

• tx_flags — feature flags enabled for this packet 🔥 like the lil badges this packet gets to wear, iykyk
• hdr_offsets — offset parameter for single queue model 💫 yes, single queue model specifically, don't forget that part
• cd_tunneling — type of tunneling enabled for single queue model 🌀 again with the single queue model, bestie, we stay consistent
• tso_len — total length of payload to segment ✂️ the whole payload, not just a piece
• mss — segment size 📏
• tso_segs — number of segments to be sent 🚀 how many lil chunks are getting yeeted out
• tso_hdr_len — length of headers to be duplicated 📋
• td_cmd — command field to be inserted into descriptor 🎯 it goes into the descriptor, periodt

💀 gentle reminder that hdr_offsets and cd_tunneling are both all about the single queue model — if you're in your splitq era, head over to the splitq struct instead, bestie 🦋

and that's the page, bestie!! 🧚 source lives over in ./drivers/net/ethernet/intel/idpf, dated October 2026, and the footer vibe is still struct idpf...fload_params(9) — mwah, go forth and build descriptors responsibly 💅🎀
