✨ Members ✨

okay so field-by-field, and imma be so real with you, each one is exactly what it sounds like 🎀

• etype — Event Type. the whole personality of the event tbh, it tells you what kind of event this is 👑
• etype_rev — Event Type Revision. the version of the event type, because even event types get revised and honestly good for them 💅
• ehl — Event Header Length. how long the header is. she comes with measurements, iconic behaviour 🌸
• ehai — Event Header Additional Info. extra info living up in the header. she's got ✨layers✨
• cntlid — Controller Identifier. which controller this belongs to, iykyk 🔥
• ets — Event Timestamp. when it happened. time-stamped, documented, main character behaviour fr fr ⭐
• pelpid — Port Identifier. which port she's repping, we love a port with identity
• rsvd16 — Reserved. do NOT touch her. she's reserved. she's staying right there in her little rsvd16[4] lane and we respect that 🫶 (hands off bestie, reserved means reserved)
• vsil — Vendor Specific Information Length. how much vendor-specific info is riding along for the trip 🦋
• el — Event Length. how long the event is, full stop, the end, the final word 😌

lowkey a whole little event record in a trench coat. highkey every field matters, so don't go skipping any of them when you're parsing 👀
