STRUCT IONIC_LIF_SETATTR_CMD(9)

🌸 struct ionic_lif_setattr_cmd — Kernel API Manual 💅

okay so bestie, picture this: you're deep in the Pensando ionic driver, and you need to tell the NIC to change a LIF attribute. That's it. That's the whole vibe. This struct is the little envelope you hand over with all the deets inside, and it's lowkey iconic for it. ✨

The manual name, for the record, is Kernel API Manual — keep that in your notes, iykyk.

🎀 NAME 🎀

struct ionic_lif_setattr_cmd — set LIF attributes on the NIC 🌸

✨ SYNOPSIS ✨

struct ionic_lif_setattr_cmd {
    u8 opcode;
    u8 attr;
    __le16 index;
    union {
      u8 state;
      char name[IONIC_IFNAMSIZ];
      __le32 mtu;
      u8 mac[6];
      __le64 features;
      struct {
        __le16 types;
        u8 key[IONIC_RSS_HASH_KEY_SIZE];
        u8 rsvd[6];
        __le64 addr;
      } rss;
      u8 stats_ctl;
      __le16 txstamp_mode;
      u8 rsvd[60];
    };
 };

🦋 Members 🦋

here's the whole cast, bestie — every field gets its moment:

• opcode — the opcode, bestie. that's the whole description. it's giving mysterious main character energy fr fr.
• attr — the attribute type (enum ionic_lif_attr) 👑
• index — the LIF index ✨
• {unnamed_union} — it's anonymous. no name, no problem. she's mysterious like that. 🙈
• state — LIF state (enum ionic_lif_state) 🎀
• name — the netdev name string, 0 terminated 🌸
• mtu — Mtu. short king field name, full-size job. 💅
• mac — station mac 🦋
• features — features (enum ionic_eth_hw_features) ⭐
• rss — RSS properties 🌈
  • rss.types — the hash types to enable (see rss_hash_types) 💜
  • rss.key — the hash secret key 🔥
  • rss.rsvd — reserved byte(s) 🫶
  • rss.addr — address for the indirection table shared memory 🧚
• stats_ctl — stats control commands (enum ionic_stats_ctl_cmd) 🍓
• txstamp_mode — TX Timestamping Mode (enum ionic_txstamp_mode) ⏰✨
• rsvd — reserved byte(s). the padding besties. they're just vibing, don't touch. 🫶

ngl, rsvd is reserved — leave her alone. reserved fields are not your little playground, no cap. 💀

that's the whole page bestie, go set some attributes 💜

this lil' note comes from ./drivers/net/ethernet/pensand… and it's dated October 2026 — so she's fresh, she's current, she's struct ionic..._setattr_cmd(9) and she ate. periodt. 🎀✨
