STRUCT PPE_SC_BYPASS(9)

✨ struct ppe_sc_bypass(9) ✨

okay so bestie, welcome to the Kernel API Manual, section 9 — we're doing the struct deep-dive today and honestly? it's giving organized. 💅

---

🌸 NAME 🌸

struct ppe_sc_bypass — PPE service bypass bitmaps. that's it, that's the whole vibe. four bitmaps, one struct, no drama. 🎀

---

🦋 SYNOPSIS 🦋

struct ppe_sc_bypass {
    unsigned long ingress[BITS_TO_LONGS( PPE_SC_BYPASS_INGRESS_SIZE)];
    unsigned long egress[BITS_TO_LONGS( PPE_SC_BYPASS_EGRESS_SIZE)];
    unsigned long counter[BITS_TO_LONGS( PPE_SC_BYPASS_COUNTER_SIZE)];
    unsigned long tunnel[BITS_TO_LONGS( PPE_SC_BYPASS_TUNNEL_SIZE)];
};

like, look at her. four unsigned long arrays, every single one sized with BITS_TO_LONGS(...) over its own PPE_SC_BYPASS_*_SIZE macro. no cap, she's symmetry personified. 👑

💖 Members 💖

• ingress — bitmap of features that can be bypassed on the ingress packet. incoming traffic said "not today" and this is the list of what's allowed to skip the line. 🚪✨
• egress — bitmap of features that can be bypassed on the egress packet. same energy, but outbound. she's leaving, and she's bypassing on the way out. 🚶‍♀️💨
• counter — bitmap of features that can be bypassed on the counter type. counters, but make it optional. 📊🦋
• tunnel — bitmap of features that can be bypassed on the tunnel packet. tunnel traffic gets its own little bypass list, because of course it does. 🕳️🌈

bestie reminder: these are bitmaps of features that can be bypassed — the manpage tells you which ones, not what happens when you flip them. don't go inventing semantics, that's how you end up in a bug report. 😭

and that's the page, bestie 💜 this one came from ./drivers/net/ethernet/qualcom... (yes the path got chopped, that's just how it is 🙈) and it's dated October 2026 — so like, future icon behavior. periodt. 💅⭐
