iwl_mei_set_nic_info(9)

💖 iwl_mei_set_nic_info(9) — the kernel API glow-up 💖

okay bestie, so this is iwl_mei_set_nic_info(9) from the Kernel API Manual, and it's genuinely the shortest little icon in the whole iwlwifi MEI saga — but she's important, so pay attention 🎀

✨ NAME ✨

iwl_mei_set_nic_info — set mac address 💅

🌸 SYNOPSIS 🌸

void iwl_mei_set_nic_info (const u8 *mac_address , const u8 *nvm_address
);

like yes, that's the whole vibe. two pointers, no return value, no drama 🦋

🫶 ARGUMENTS 🫶

• mac_address — the mac address you wanna set, bestie. it's a const u8 *, so you're handing over a pointer to the bytes — not copying them, not owning them, just pointing, iykyk ✨
• nvm_address — the NVM mac address you wanna set. also a const u8 *, also just a pointer to the bytes 🍓

👑 DESCRIPTION 👑

so the tea is: this function must be called upon mac address change. that's it. that's the whole description. "must" — not "should", not "maybe if you feel like it" — must 🔥

lowkey the emphasis is doing a lot of work here, but the manpage says it, so I'm saying it: mac address changes go through iwl_mei_set_nic_info. periodt 💅
