STRUCT IWL_SAP_NOTIF_HOST_LINK_UP(9)

💅 struct iwl_sap_notif_host_link_up

okay bestie, so this is the manual for struct iwl_sap_notif_host_link_up — and ngl the whole thing is literally just the payload of %SAP_MSG_NOTIF_HOST_LINK_UP. That's it, that's the vibe. It's giving "I exist to carry data for a notification" energy and honestly? iconic.

It lives in the Kernel API Manual, and we're about to get into every single field like the obsessed little gremlin we are. 🫶

✨ SYNOPSIS ✨

struct iwl_sap_notif_host_link_up {
    struct iwl_sap_hdr hdr;
    struct iwl_sap_notif_connection_info conn_info;
    u8 colloc_channel;
    u8 colloc_band;
    __le16 reserved;
    u8 colloc_bssid[6];
    __le16 reserved1;
};

🎀 Members (the cast of this little struct drama) 🎀

• hdr — The SAP header. It's the main character that sets everything up, periodt. 👑
• conn_info — All the tea about the connection. Info, but make it connection-flavored. 💖
• colloc_channel — The collocated channel. Literally just the channel that's collocated. slay.
• colloc_band — The band of the collocated channel. So like, which band that collocated channel is vibing in. 🌈
• reserved — For alignment. It's not here to be interesting, it's here to do a job. respect. 🫡
• colloc_bssid — The collocated BSSID. It's a [6] array and it's doing great. no cap.
• reserved1 — For alignment. Again. Padding's loyal sidekick, fr fr.

okay that's literally everyone, bestie. the whole sap.h crew. don't come for me about the length, I didn't write the kernel. 💀

and that's the whole page! 🦋 source/version vibes come from ./drivers/net/wireless/intel/i... and we're stamping this bad boy October 2026, page title struct iwl_...host_link_up(9) — go forth and know ur payload fields, queen. 💜✨
