STRUCT DPSW_VLAN_IF_CFG(9)

💅 struct dpsw_vlan_if_cfg(9) — like, the whole kernel API manual moment 🎀

okay bestie, so this is a page from the Kernel API Manual, and today's main character is struct dpsw_vlan_if_cfg — literally the "Set of VLAN Interfaces" struct. no cap, that's its whole NAME: struct dpsw_vlan_if_cfg - Set of VLAN Interfaces. she's a little bundle of interfaces that belong to a VLAN's egress list, and we're gonna go through her field by field like we're doing a vibe check on her whole personality. ✨

---

🌸 SYNOPSIS 🌸

here's the shape of her, bestie — copy it exactly, don't be out here renaming things:

struct dpsw_vlan_if_cfg {
    u16 num_ifs;
    u16 options;
    u16 if_id[DPSW_MAX_IF];
    u16 fdb_id;
 };

that's it. four fields. tiny struct, huge energy. 💜

🦋 Members 🦋

every member, one by one, no skipping, iykyk:

• num_ifs — the number of interfaces that are assigned to the egress list for this VLAN. like, how many besties are actually in the group chat. 🫶
• options — the options map for this command, and yes the one that matters here is DPSW_VLAN_ADD_IF_OPT_FDB_ID. that's the flag, that's the vibe. ⭐
• if_id — the actual set of interfaces that are assigned to the egress list for this VLAN. this is the squad roster, array style, sized DPSW_MAX_IF. 👑
• fdb_id — the FDB id that this VLAN is gonna use on these specific interfaces — but hmm, heads up, it's taken into account only if the DPSW_VLAN_ADD_IF_OPT_FDB_ID is specified in the options field. so if you didn't set that option? this field is lowkey just sitting there, existing, unbothered. 🙈

and that's the whole page, bestie!! 🎀 one last lil sign-off moment: this beauty came from the kernel file at ./drivers/net/ethernet/freesca... (yeah, it's abbreviated in the footer, don't come for me 💀) and it's dated October 2026. slay. go read your structs. 💖
