UNION IONIC_PORT_IDENTITY(9)

💖 union ionic_port_identity 💖

okay so bestie, welcome to the Kernel API Manual — yes that's the manual name, and yes this page is a whole vibe. We're looking at union ionic_port_identity, which the NAME section describes very simply as a port identity structure ✨. That's it. That's the pitch. But like… it's so much more than that, iykyk. 🦋

✨ SYNOPSIS ✨

here's the shape of it, and listen — do not retype this by hand, copy it exactly fr fr:

union ionic_port_identity {
    struct {
      u8 version;
      u8 type;
      u8 num_lanes;
      u8 autoneg;
      __le32 min_frame_size;
      __le32 max_frame_size;
      u8 fec_type[4];
      u8 pause_type[2];
      u8 loopback_mode[2];
      __le32 speeds[16];
      u8 rsvd2[44];
      union ionic_port_config config;
    };
    __le32 words[478];
 };

see how it's a union with an anonymous struct inside AND a words array? main character energy, honestly. It literally cannot decide if it's a struct or an array, and honestly? relatable. 💅

🎀 MEMBERS 🎀

here's the whole cast, one by one, no skipping, no cap:

• {unnamed_struct} — anonymous. that's the whole description. it's anonymous, bestie. it has no name. it's mysterious. 🕵️‍♀️
• version — identity structure version ✨
• type — type of port, typed as enum ionic_port_type 🫶
• num_lanes — number of lanes for the port 🌈
• autoneg — autoneg supported ⭐
• min_frame_size — minimum frame size supported 🍓
• max_frame_size — maximum frame size supported 🍓 (they're a matched set, obsessed)
• fec_type — supported fec types 🔥
• pause_type — supported pause types 💜
• loopback_mode — supported loopback mode 🦋
• speeds — supported speeds, and it's an array of <italic>16 __le32 values</italic> 👑
• rsvd2 — reserved byte(s) 🙈 — like, don't touch, it's saving seats
• config — current port configuration, and it's a union ionic_port_config 💖
• words — word access to struct contents — this is the __le32 words[478] twin, so you can peek at the whole thing as raw words 😭

like… that's the entire extended universe. ate and left no crumbs. 💀

ngl bestie, that's genuinely the whole page — the source path shows up truncated as ./drivers/net/ethernet/pensand... in the footer, and the date on it is October 2026, so go read it in the future, i guess? 🧚 anyway, that's the sign-off: source/version ./drivers/net/ethernet/pensand..., dated October 2026, union ionic_port_identity(9) — periodt 💖🎀🫶
