STRUCT IWL_SAP_NVM(9)

💖 struct iwl_sap_nvm(9) 💖

okay bestie, welcome to the struct iwl_sap_nvm(9) page from the Kernel API Manual — yes that's the whole title, she's a kernel API manual girly and she's serving documentation realness ✨

---

🎀 NAME 🎀

struct iwl_sap_nvm — the payload for %SAP_MSG_NOTIF_NVM. that's it, that's the vibe check 💅

---

✨ SYNOPSIS ✨

here's the whole struct, copy it exactly pls, no typos, we are NOT getting yelled at by the compiler today:

struct iwl_sap_nvm {
    struct iwl_sap_hdr hdr;
    u8 hw_addr[6];
    u8 n_hw_addrs;
    u8 reserved;
    __le32 radio_cfg;
    __le32 caps;
    __le32 nvm_version;
    __le32 channels[110];
 };

look at her. iconic. eleven lines of pure main character energy 👑

🌸 Members 🌸

okay so let's go member by member, no skipping, every single one gets her moment:

• hdr — the SAP header. the little intro card at the top of the struct fr 🫶
• hw_addr — the MAC address. six whole bytes of identity 💖
• n_hw_addrs — the number of MAC addresses. count 'em, bestie 🔢
• reserved — for alignment. she's not here for the plot, she's here so everything lines up correctly, and honestly? respect 🙈
• radio_cfg — the radio configuration. the radio is configured, slay 📻
• caps — see enum iwl_sap_nvm_caps. go read that one, iykyk
• nvm_version — the version of the NVM. gotta know which version you're on, always 🌈
• channels — the data for each channel. and it's channels[110], so yes, 110 of them. one hundred and ten. she said go big or go home ⭐

quick heads up bestie: everything on this page is exactly what the original says — i'm just here to make it fun, not to invent new behaviour. don't come for me 🔥

and that's a wrap, gorgeous 🌸 this page came from the Kernel API Manual, source ./drivers/net/wireless/intel/i..., dated October 2026, and it signed off as struct iwl_sap_nvm(9) — so like, shoutout to that footer, she ate 💅💖 mwah, go read some kernel headers, ily 🫶
