STRUCT IONIC_PORT_SETATTR_CMD(9)

🎀 struct ionic_port_setattr_cmd(9) 🎀

okay bestie, welcome to the Kernel API Manual 💖 — this is the page for struct ionic_port_setattr_cmd, and yes it's giving "one struct, so many options, so little time." Let's get into it ✨

---

🌸 NAME 🌸

struct ionic_port_setattr_cmd — set port attributes on the NIC 👑 literally the "hey NIC, change this about your port" command packet, no cap.

---

✨ SYNOPSIS ✨

here's the whole vibe, copied exactly so you can trust it 🫶:

struct ionic_port_setattr_cmd {
    u8 opcode;
    u8 index;
    u8 attr;
    u8 rsvd;
    union {
      u8 state;
      __le32 speed;
      __le32 mtu;
      u8 an_enable;
      u8 fec_type;
      u8 pause_type;
      u8 loopback_mode;
      u8 stats_ctl;
      u8 rsvd2[60];
    };
 };

like… look at her. she's compact, she's union-y, she's iconic 💅

---

🦋 Members 🦋

okay so every single field, and what it's actually for 👇

• opcode — Opcode. the "what am I even doing" byte 🎯
• index — Port index. which port we're talking to, iykyk
• attr — Attribute type (enum ionic_port_attr). this is the picker — it decides which member of the union below is the one that matters
• rsvd — reserved byte(s). not yours, don't touch 🙈

🧚 {unnamed_union}

anonymous — she has no name, only range 💜

• state — Port state
• speed — Port speed
• mtu — Port MTU
• an_enable — Port autonegotiation setting
• fec_type — Port FEC type setting
• pause_type — Port pause type setting
• loopback_mode — Port loopback mode
• stats_ctl — Port stats setting
• rsvd2 — reserved byte(s). again: reserved. hands off 😭

real talk: rsvd2 is u8 rsvd2[60] — that's sixty whole reserved bytes, it's not a suggestion, it's a boundary 🚧

this list is long long, so buckle up, bestie — every single one, in order, no cuts, no skips, periodt 💀✨
