STRUCT DPSW_ATTR(9)

🌸 NAME 🌸

okay bestie, gather ’round: this is struct dpsw_attr(9) from the Kernel API Manual, and it’s literally the structure representing DPSW attributes. she’s giving “main character energy” and we’re obsessed. 💅✨

✨ SYNOPSIS ✨

       struct dpsw_attr {
           int id;
           u64 options;
           u16 max_vlans;
           u8 max_meters_per_if;
           u8 max_fdbs;
           u16 max_fdb_entries;
           u16 fdb_aging_time;
           u16 max_fdb_mc_groups;
           u16 num_ifs;
           u16 mem_size;
           u16 num_vlans;
           u8 num_fdbs;
           enum dpsw_component_type component_type;
           enum dpsw_flooding_cfg flooding_cfg;
           enum dpsw_broadcast_cfg broadcast_cfg;
        };

okay so here’s the whole cast, no cap — every single one matters:

• id — DPSW object ID.
• options — Enable/Disable DPSW features.
• max_vlans — Maximum Number of VLANs.
• max_meters_per_if — Number of meters per interface.
• max_fdbs — Maximum Number of FDBs.
• max_fdb_entries — Number of FDB entries for default FDB table; 0 - indicates default 1024 entries.
• fdb_aging_time — Default FDB aging time for default FDB table; 0 - indicates default 300 seconds.
• max_fdb_mc_groups — Number of multicast groups in each FDB table; 0 - indicates default 32.
• num_ifs — Number of interfaces.
• mem_size — DPSW frame storage memory size.
• num_vlans — Current number of VLANs.
• num_fdbs — Current number of FDBs.
• component_type — Component type of this bridge.
• flooding_cfg — Flooding configuration (PER_VLAN - default, PER_FDB).
• broadcast_cfg — Broadcast configuration (PER_OBJECT - default, PER_FDB).
