STRUCT IWL_RSS_CONFIG_CMD(9)

💖 struct iwl_rss_config_cmd(9) 💖

okay so bestie, welcome to the Kernel API Manual — we're talking about struct iwl_rss_config_cmd, and it's literally the RSS (Receive Side Scaling) configuration glow-up 🦋. no cap, it's giving "let me spread this receive traffic across my queues" main character energy.

✨ NAME ✨

struct iwl_rss_config_cmd — RSS (Receive Side Scaling) configuration 👑

🌸 SYNOPSIS 🌸

struct iwl_rss_config_cmd {
    __le32 flags;
    u8 hash_mask;
    u8 reserved[3];
    __le32 secret_key[IWL_RSS_HASH_KEY_CNT];
    u8 indirection_table[IWL_RSS_INDIRECTION_TABLE_SIZE];
 };

like, that's the whole struct, and every field is doing its little job. we love a functional icon 💅

🎀 Members 🎀

• flags — 1 means enable, 0 means disable. that's it, that's the toggle 🫶
• hash_mask — the type of RSS to use. values come from iwl_rss_hash_func_en, so go check that enum, iykyk ✨
• reserved — reserved. literally just vibing there, don't touch it 🙈
• secret_key — the 320 bit input of random key configuration from the driver 🔥🔐
• indirection_table — the indirection table. it's the indirection table. iconic behaviour tbh 💀

fr fr go read those too, they're all in the same friend group and the lore runs deep 😭

mwah, that's the whole page bestie 💖 this little writeup shipped from ./drivers/net/wireless/intel/i... in October 2026, and it's filed under struct iwl_rss_config_cmd(9) — slay, go configure some RSS 🌈⭐
