STRUCT ICE_DYNAMIC_PORT(9)

💅 struct ice_dynamic_port(9) — from the Kernel API Manual, bestie

okay so picture this: it's a whole 9 manpage, kernel API manual energy, and the star of the show is struct ice_dynamic_port — the little bookkeeping baddie that keeps track of a dynamically added devlink port instance. yes, that one. she's got a header, she's got a footer, she's got lore. let's get into it 🫶

---

✨ NAME ✨

struct ice_dynamic_port — literally the struct that tracks a dynamically added devlink port instance. that's her job. that's her whole personality. 🎀

---

✨ SYNOPSIS ✨

struct ice_dynamic_port {
    u8 hw_addr[ETH_ALEN];
    u8 active: 1;
    u8 attached: 1;
    struct devlink_port devlink_port;
    struct ice_pf *pf;
    struct ice_vsi *vsi;
    unsigned long repr_id;
    u32 sfnum;
    union {
      struct ice_sf_dev *sf_dev;
    };
 };

look at her. every field accounted for, nothing invented, nothing skipped. icon behavior only 👑

✨ Members ✨

• hw_addr — the HW address for this port. it's giving "where do I actually live" 🏠
• active — true if the port has been activated. she's awake, she's online, she's serving 🌸
• attached — true if the prot is attached. (yes, the page literally says "prot" — typo era, we respect the original spelling ✋😭 the meaning is: the port is attached.)
• devlink_port — the associated devlink_port structure. her plus-one, her ride-or-die 💖
• pf — pointer to the PF private structure. hi bestie 👋
• vsi — the VSI associated with this port. the group chat she belongs to 🦋
• repr_id — the representor ID. her government name, lowkey 💅
• sfnum — the subfunction ID. second name, just as valid 🔥
• {unnamed_union} — anonymous. a mystery. we love a private queen 🙈
  • sf_dev — pointer to the subfunction device. the actual device in question ✨

---

✨ Description ✨

an instance of a dynamically added devlink port. Each port flavour — and that's exactly where the original page's sentence stops, bestie, so that's where ours stops too. no cap, no invented endings, we don't do fanfiction in the kernel docs. 💀

---

✨ SEE ALSO ✨

• Kernel file ./drivers/net/ethernet/intel/ice/devlink/port.h — go read the source, iykyk 📖

---

real talk though: this is a kernel API manual page, so if you're poking at ice_dynamic_port fields, you're already deep in the intel ice driver devlink port code. slay, but carefully. 🌈

---

and that's the whole page, bestie — no details dropped, no flags invented, all vibes intact. this iconic little number came from source/version ./drivers/net/ethernet/intel/i... (yes, truncated in the original, we don't fix what we didn't break) and it's dated October 2026, which honestly? future icon behavior. ⭐💜
