👑 Members 👑

okay here's the field-by-field rundown, no skips, no shortcuts, we respect every single member in this house:

• status_type — the type of unsolicited status. yes bestie, type of unsolicited status. 🙈
• status_subtype — and the subtype of unsolicited status. the subcategory. the little sibling. 💅
• d_id — destination ID 🎯
• lun — logical unit number, the classic
• queue_designator — queue designator ✨
• length — buffer length 📏
• res1 — reserved field 1 (it's reserved, don't touch, we don't ask questions) 💀
• res2 — reserved field 2 🫶
• class — class of service 🌈
• res3 — reserved field 3 🧚
• s_id — source ID, matching energy with d_id obviously 💜
• res4 — reserved field 4, the finale, the last reserved one, we stan a consistent naming scheme ⭐

ngl bestie, those res1 through res4 fields are reserved — that means hands off, they're not yours to fill in, okay? 😭
