STRUCT CODEL_PARAMS(9)

🌸 struct codel_params(9) 🌸

okay bestie, welcome to the Kernel API Manual — yes, that's the manual name, and yes, we're reading kernel docs together, it's giving study date energy 💅

---

✨ NAME ✨

struct codel_params — literally just a little struct that contains codel parameters 🎀 no cap, that's the whole vibe.

---

🦋 SYNOPSIS 🦋

struct codel_params {
    codel_time_t target;
    codel_time_t ce_threshold;
    codel_time_t interval;
    u32 mtu;
    bool ecn;
    u8 ce_threshold_selector;
    u8 ce_threshold_mask;
 };

look at her. seven fields. absolute main character energy 👑

💖 Members 💖

• target — the target queue size, measured in time units ⏱️ (yes bestie, time, not bytes — iykyk)
• ce_threshold — the threshold for marking packets with ECN CE, lowkey the bouncer at the club deciding who gets marked 🚪✨
• interval — the width of the moving time window, like a lil sliding window of time, so cozy 🪟
• mtu — the device mtu, or the minimal queue backlog in bytes. two jobs, one field, she's versatile 🫶
• ecn — is Explicit Congestion Notification enabled? a whole bool just to answer that 🙈
• ce_threshold_selector — apply ce_threshold to packets matching this value in the diffserv/ECN byte of the IP header 🎯 like a very specific little filter
• ce_threshold_mask — the mask to apply to the ce_threshold_selector comparison 🎭 masking, but make it networking

---

🌈 SEE ALSO 🌈

• Kernel file ./include/net/codel.h
• struct codel_vars(9)
• struct codel_stats(9)

go read those too, they're the rest of the friend group fr fr 🫶

---

💀 reminder: ce_threshold_selector and ce_threshold_mask work together — one picks, one masks. don't use just one and expect magic, bestie, that's not how the comparison works.

and that's the whole page, babes 💜 this lil gem lives under ./include/net and the manual says October 2026 — so like, see you in the future?? 🌸 signing off, struct codel_params(9), mwah 💅🎀
