STRUCT IWL_TRANS_INFO(9)

✨ struct iwl_trans_info(9) ✨

okay bestie, welcome to the Kernel API Manual — yes, we're doing kernel pages now, and honestly? this one's a cutie. it's the little struct that carries all the transport info the outside world is allowed to peek at. 🫶

---

🌸 NAME 🌸

struct iwl_trans_info — transport info for outside use. that's it. that's the whole vibe. it's the "here's what you're allowed to know" bag of goodies. 💅

---

✨ SYNOPSIS ✨

struct iwl_trans_info {
    const char *name;
    u32 max_skb_frags;
    u32 hw_rev;
    u32 hw_rev_step;
    u32 hw_rf_id;
    u32 hw_crf_id;
    u32 hw_cnv_id;
    u32 hw_id;
    u8 pcie_link_speed;
    u8 num_rxqs;
 };

look at her. ten fields, not one of them wasted. iconic. 👑

🎀 Members 🎀

• name — the device name. literally just what the device calls itself, no cap. 🏷️
• max_skb_frags — the maximum number of fragments an SKB can have when it's transmitted. and here's the tea: 0 means frag SKBs (NETIF_F_SG) aren't supported at all — so zero is not a "no limit" situation, it's a "we don't do that here" situation. remember that. 💀
• hw_rev — the revision data of the HW. the hardware's whole resumé, basically.
• hw_rev_step — The mac step of the HW. (yes, capital T, capital mac step, it's giving official.) 🌟
• hw_rf_id — the device RF ID. 🦋
• hw_crf_id — the device CRF ID.
• hw_cnv_id — the device CNV ID. (three IDs in a row, she's thorough, we love a thorough queen.)
• hw_id — the ID of the device / sub-device. and the bit math matters, so listen up bestie: Bits 0:15 represent the sub-device ID, and Bits 16:31 represent the device ID. two IDs, one field, she's efficient. 🧚
• pcie_link_speed — current PCIe link speed (PCI_EXP_LNKSTA_CLS_*). ⚠️ only valid for discrete (not integrated) NICs — so if you're on an integrated one, this value is not your story, don't @ her.
• num_rxqs — number of RX queues allocated by the transport. count 'em. 🔥

ngl this page is short but she ate. no filler, all facts, and the facts are load-bearing. 🍓

and that's a wrap, bestie! 💖 this lil masterpiece came from ./drivers/net/wireless/intel/i... and it's dated October 2026 — go forth and transport responsibly. 🌈⭐
