STRUCT MXL862XX_CTP_PORT_ASSIGNMENT(9)

💅 struct mxl862xx_ctp_port_assignment — Kernel API Manual ✨

okay so bestie, welcome to the glow-up doc for struct mxl862xx_ctp_port_assignment(9) 🎀 — it's the CTP Port Assignment / association-with-logical-port situation, and honestly it's giving "matchmaker for ports" energy. Let's get into it 🦋

---

🌸 NAME 🌸

struct mxl862xx_ctp_port_assignment — CTP Port Assignment/association with logical port 💖

---

✨ SYNOPSIS ✨

ok so here's the whole struct, every field, exactly as it lives:

struct mxl862xx_ctp_port_assignment {
    u8 logical_port_id;
    __le16 first_ctp_port_id;
    __le16 number_of_ctp_port;
    __le32 mode;
    __le16 bridge_port_id;
};

---

🫶 Members (the main characters) 👑

• logical_port_id — the Logical Port Id, bestie 💫. Heads up tho: the valid range is hardware dependent, so don't come for me if your chip's vibes are different, okay? 🙈
• first_ctp_port_id — the First CTP (Connectivity Termination Port) ID that gets mapped to the logical port ID above ⭐. Like, the first one in the squad 🫶
• number_of_ctp_port — the Total number of CTP Ports mapped above that logical port ID 🔥. All of them. The whole group chat 💅
• mode — the logical port mode, and it's the one that defines the sub interface ID format 🌈. See enum mxl862xx_logical_port_mode for the deets, iykyk 👀
• bridge_port_id — the Bridge Port ID (not FID, ok, don't mix them up, that's a different thing entirely 😭). For allocation, each CTP allocated is mapped to the Bridge Port given by this field 🎀. And the Bridge Port will be configured to use first_ctp as the egress CTP — iconic behaviour honestly 👑
