STRUCT DPSW_LAG_CFG(9)

💅 struct dpsw_lag_cfg(9) — the Kernel API Manual moment

okay so bestie, welcome to the glow-up era of struct dpsw_lag_cfg(9) — this is the Kernel API Manual page for the config struct you use when you're setting up a LAG group. it's giving "small struct, big responsibilities" energy and honestly? iconic. 🎀

---

✨ NAME ✨

struct dpsw_lag_cfg — Configuration structure for a LAG group. yes, that's it. that's the whole vibe. 🔥

---

🌸 SYNOPSIS 🌸

here's the struct, exactly as it lives, no edits no notes:

struct dpsw_lag_cfg {
    u8 group_id;
    u8 num_ifs;
    u8 if_id[DPSW_MAX_LAG_IFS];
    u8 phase;
 };

look at her. four little members, one big job. 🦋

---

💖 Members 💖

• group_id — this is the Link aggregation group ID, bestie. valid values are in the [1, DPSW_MAX_LAG_IFS] range. so like... 1 on up to DPSW_MAX_LAG_IFS, and nothing outside that, no cap. 👑
• num_ifs — how many interfaces are in this LAG group. the valid range is [0, DPSW_MAX_LAG_IFS]. (yes, 0 is allowed. we love a flexible queen.) 🌸
• if_id — an array holding the interface IDs of the ports that are part of a LAG group. it's u8 if_id[DPSW_MAX_LAG_IFS] sized, so it's ready for the whole squad. 🫶
• phase — use DPSW_LAG_SET_PHASE_APPLY if you're actually processing LAG configuration, or DPSW_LAG_SET_PHASE_CHECK if you're just validating it. apply vs. check, processing vs. validation — pick your moment, main character. ⭐

lowkey a reminder: group_id starts at 1 — there's no LAG group 0 era. and num_ifs can go down to 0. that's literally what the page says, so don't come for me. 💀

and that's the page, bestie! 🧚 this one comes straight from ./drivers/net/ethernet/freesca... and it's dated October 2026 — so yeah, she's fresh, she's documented, and she's serving struct dpsw_lag_cfg(9) realness. mwah. 💅✨🍓
