STRUCT MXL862XX_BRIDGE_CONFIG(9)

🎀 struct mxl862xx_bridge_config(9) 🎀

okay so this is a page straight out of the Kernel API Manual, and bestie, it's literally the blueprint for a bridge config struct. it's giving "networking but make it structured" 💅 no cap, every field here matters, so let's get into it 🫶

---

✨ NAME ✨

struct mxl862xx_bridge_config — Bridge Configuration 😌 that's it, that's the whole vibe. it's the struct that holds a bridge's configuration. iconic.

---

🌸 SYNOPSIS 🌸

okay here's the actual shape of it, copied exactly because we do NOT freestyle struct definitions in this house 🧚

struct mxl862xx_bridge_config {
    __le16 bridge_id;
    __le32 mask;
    u8 mac_learning_limit_enable;
    __le16 mac_learning_limit;
    __le16 mac_learning_count;
    __le32 learning_discard_event;
    u8 sub_metering_enable[MXL862XX_BRIDGE_PORT_EGRESS_METER_MAX];
    __le16 traffic_sub_meter_id[MXL862XX_BRIDGE_PORT_EGRESS_METER_MAX];
    __le32 forward_broadcast;
    __le32 forward_unknown_multicast_ip;
    __le32 forward_unknown_multicast_non_ip;
    __le32 forward_unknown_unicast;
};

💖 Members 💖

okay bestie, field by field, no skipping, we're doing all twelve 💀

• bridge_id — the Bridge ID (FID). that's its whole job, and it ate 💅
• mask — the mask, bestie. for the actual deets go look at enum mxl862xx_bridge_config_mask.
• mac_learning_limit_enable — the lil switch that enables MAC learning limitation. on or off, no in-between 🌈
• mac_learning_limit — the max number of MAC addresses that can be learned in this bridge. and note: that's all bridge ports, not per-port. the whole bridge, together, as a team 🫶
• mac_learning_count — the number of MAC addresses learned from this bridge. the actual tally ✨
• learning_discard_event — the number of learning discard events that happened because a hardware resource was not available. sad but important 😭
• sub_metering_enable — array (sized MXL862XX_BRIDGE_PORT_EGRESS_METER_MAX) that says whether traffic metering applies on a type of traffic — think broadcast, multicast, unknown unicast, etc. ⭐
• traffic_sub_meter_id — also an array, [MXL862XX_BRIDGE_PORT_EGRESS_METER_MAX]. this is the meter for bridge process with a specific type (broadcast, multicast, unknown unicast, etc.) 🔥
• forward_broadcast — the forwarding mode of broadcast traffic. see enum mxl862xx_bridge_forward_mode.
• forward_unknown_multicast_ip — the forwarding mode of unknown multicast IP traffic. see enum mxl862xx_bridge_forward_mode.
• forward_unknown_multicast_non_ip — the forwarding mode of unknown multicast non-IP traffic. see enum mxl862xx_bridge_forward_mode. (yes, non-IP is a whole separate field, she's not like the others 💅)
• forward_unknown_unicast — the forwarding mode of unknown unicast traffic. see enum mxl862xx_bridge_forward_mode.
