STRUCT IONIC_LIF_GETATTR_COMP(9)

💅 struct ionic_lif_getattr_comp(9) — Kernel API Manual 🎀

okay bestie, buckle up, because this is a page straight outta the Kernel API Manual and it's all about one very specific little struct: struct ionic_lif_getattr_comp — the LIF get attr command completion. that's it, that's the whole vibe. it's the thing that comes back at you when the get-attr command finishes doing its thing. iconic behavior honestly 💖

---

✨ SYNOPSIS ✨

here's the whole shape of it, character for character, no cap:

struct ionic_lif_getattr_comp {
    u8 status;
    u8 rsvd;
    __le16 comp_index;
    union {
      u8 state;
      __le32 mtu;
      u8 mac[6];
      __le64 features;
      __le16 txstamp_mode;
      u8 rsvd2[11];
    };
    u8 color;
 };

look at her. flawless. not a single byte out of place 🫶

🌸 Members 🌸

okay so now we go field by field, and yes i'm gonna be normal about it (i will not be normal about it):

• status — the status of the command, and it's an enum ionic_status_code. this is the vibe check of the whole operation: did it slay or did it flop 😭
• rsvd — reserved byte(s). literally just sitting there being reserved. main character energy of doing nothing but looking pretty 💅
• comp_index — the index in the descriptor ring for which this is the completion. this is the "you are here 📍" of the ring, iykyk.
• {unnamed_union} — anonymous. that's literally all it says. an unnamed union just vibing. mysterious. unknowable. we love her 🙈

then inside that anonymous union, bestie, there's a whole little friend group:

• state — the LIF state, typed as enum ionic_lif_state.
• mtu — Mtu. yes that's the whole description. short and iconic ✨
• mac — the station mac. six whole bytes of it: u8 mac[6].
• features — features, typed as enum ionic_eth_hw_features.
• txstamp_mode — the TX Timestamping Mode, typed as enum ionic_txstamp_mode.
• rsvd2 — reserved byte(s). the sequel. the reserved-again. u8 rsvd2[11] out here taking up space and serving absolutely zero 💀

• color — the color bit. yes queen, even the completion gets a little pop of color 🌈

heads up: all of those union members share the same space, so it's one or the other depending on what you're reading — that's just how a union works, that's not me being dramatic, that's C 😌
