STRUCT IEEE802154_ADDR(9)

✨ struct ieee802154_addr 💅

okay so bestie, welcome to the Kernel API Manual — this is the page for struct ieee802154_addr, aka the IEEE802.15.4 device address 🎀. it's giving "tiny struct, big responsibilities" and honestly we're obsessed. let's get into it 💖

✨ SYNOPSIS ✨

struct ieee802154_addr {
    u8 mode;
    __le16 pan_id;
    union {
      __le16 short_addr;
      __le64 extended_addr;
    };
 };

look at her. neat, tidy, doing exactly what she needs to do 🫶

🌸 Members 🌸

• mode — the address mode, straight out of the frame header 👑. it can be one of these three, no cap:
  • IEEE802154_ADDR_NONE
  • IEEE802154_ADDR_SHORT
  • IEEE802154_ADDR_LONG
• pan_id — the PAN ID that this address belongs to 💫. that's her home base.
• {unnamed_union} — it's anonymous, it has no name, it simply exists ✨ main character energy fr fr.
• short_addr — the address, but only when mode is IEEE802154_ADDR_SHORT. little and cute 🍓
• extended_addr — the address when mode is IEEE802154_ADDR_LONG. big girl, 64 bits, ate 💅

ngl the union is the whole vibe check here — which member is "the" address depends entirely on what mode says, so read mode first before you go grabbing addresses. iykyk 🔥
