ENUM IWL_MEI_PAIRWISE_CIPHER(9)

💖 NAME 💖

enum iwl_mei_pairwise_cipher — bestie, this is the cipher for the UCAST key. that's the whole vibe ✨

okay so real quick — this is a page out of the Kernel API Manual, so you know it's legit. let's get into it 🫶

✨ SYNOPSIS ✨

enum iwl_mei_pairwise_cipher {
    IWL_MEI_CIPHER_NONE ,
    IWL_MEI_CIPHER_TKIP ,
    IWL_MEI_CIPHER_CCMP ,
    IWL_MEI_CIPHER_GCMP ,
    IWL_MEI_CIPHER_GCMP_256

};

like, that's the whole enum, no notes 💅

🎀 Constants 🎀

okay so these are your five members, and they are literally just vibes with names:

• IWL_MEI_CIPHER_NONE — none 😌
• IWL_MEI_CIPHER_TKIP — tkip
• IWL_MEI_CIPHER_CCMP — ccmp
• IWL_MEI_CIPHER_GCMP — gcmp
• IWL_MEI_CIPHER_GCMP_256 — gcmp 256

that's it. that's the list. slay 💅

🦋 Description 🦋

⚠️ important lore alert ⚠️ note that those values are dictated by the CSME firmware API (see sap.h)

like, not me making up numbers — the CSME firmware said what it said and we're respecting it, periodt. if you're out here reordering them or inventing your own, that's a no from me 🙈

okay that's the page!! quick sign-off before you go: this one came from ./drivers/net/wireless/intel/i... (yes it's truncated like that in the source, don't come for me 😭), dated October 2026, and the page is titled enum iwl_mei...rwise_cipher(9). mwah, go forth and cipher responsibly 💖🎀✨
