STRUCT PPE_SC_CFG(9)

🌸 struct ppe_sc_cfg(9) 🌸

okay bestie, we're in the Kernel API Manual today and this one is literally about PPE service code configuration 💅 (that's struct ppe_sc_cfg, for the people in the back 🫶). Buckle up, it's giving very niche networking energy and honestly? obsessed.

✨ NAME ✨

struct ppe_sc_cfg — PPE service code configuration. that's it, that's the vibe 🎀

---

🦋 SYNOPSIS 🦋

struct ppe_sc_cfg {
    bool dest_port_valid;
    int dest_port;
    struct ppe_sc_bypass bitmaps;
    bool is_src;
    int next_service_code;
    int eip_field_update_bitmap;
    int eip_hw_service;
    int eip_offset_sel;
 };

copy it exactly, no cap, don't be out here retyping it from memory 😭

👑 Members 👑

• dest_port_valid — do we generate a destination port or not? yes/no energy, a literal bool slay ✅
• dest_port — the destination port ID, the main character of this field ngl 🌟
• bitmaps — a struct ppe_sc_bypass holding the bitmap of bypass features 💫
• is_src — the destination port acts as a source port, and the packet gets sent to the CPU 🖥️ (iykyk)
• next_service_code — the new service code that gets generated, fresh out the oven 🍓
• eip_field_update_bitmap — which fields get updated as actions are taken for EIP 📝
• eip_hw_service — the hardware functions selected for EIP 🔥
• eip_offset_sel — packet offset selection: you're either using the packet's layer 4 offset or the packet's layer 3 offset for EIP, pick your fighter 🥊

---

💜 Description 💜

so here's the tea 🫖: the service code is generated while the packet is passing through PPE. that's the whole description. short, sweet, iconic, periodt ✨

no warnings, no bugs, no exit statuses on this one — just pure struct goodness. but do keep every field spelled exactly right, fr fr 🙈

and that's the whole page! footer deets for the record: source is ./drivers/net/ethernet/qualcom... and the date on it is October 2026, page is struct ppe_sc_cfg(9). mwah, ily, go configure some service codes 💅🎀⭐
