STRUCT DPSW_FDB_ATTR(9)

💅 struct dpsw_fdb_attr(9) — like, the FDB attributes era 🎀

okay so this is from the Kernel API Manual bestie, and it's literally the struct that holds all the FDB attributes for dpsw. no cap, it's giving "small struct, big responsibilities" energy ✨

---

✨ NAME ✨

struct dpsw_fdb_attr — FDB Attributes 🦋 (yes that's the whole name, she's concise, we love that for her)

---

🌸 SYNOPSIS 🌸

struct dpsw_fdb_attr {
    u16 max_fdb_entries;
    u16 fdb_ageing_time;
    enum dpsw_learning_mode learning_mode;
    u16 num_fdb_mc_groups;
    u16 max_fdb_mc_groups;
 };

like, five fields. five. and every single one of them is iconic in her own way 💅

---

👑 Members 👑

• max_fdb_entries — the number of FDB entries. that's it, that's the field. it's a u16, she's little but she counts 🍓
• fdb_ageing_time — the ageing time, measured in seconds. yes, seconds. not millis, not jiffies, seconds. iykyk 😭
• learning_mode — the learning mode, and it's an enum dpsw_learning_mode. slay, an enum, we stan type safety 🫶
• num_fdb_mc_groups — the current number of multicast groups. like right now, in this moment, main character energy 🌈
• max_fdb_mc_groups — the maximum number of multicast groups. the ceiling. the limit. the "don't push her" number 💀

okay bestie, buckle up, this list is LONG and we're getting through all of it because every single one of these is a link and we do not skip links in this house 💖

the kernel file lives at ./drivers/net/ethernet/freescale/dpaa2/dpsw.h — go read her, she's the source of truth 📖

ngl bestie that's forty whole cross-references. forty. she said "here's my entire social circle" and dumped the group chat 🧚

mwah 💋 that's the page! sourced straight from ./drivers/net/ethernet/freesca... (yes the path gets truncated, she's mysterious like that 🙈) and dated October 2026 — future girlie behavior, honestly. go forth and configure your FDBs, you absolute icon 👑✨
