⭐ SYNOPSIS ⭐

🎀 ARGUMENTS 🎀

• gt — the xe_gt. that's the graphics tile situation, literally the main character of this whole call 🦋
• vfid — the VF identifier. it's a u32, and it's how we know which virtual function we're talking about 💖

🔥 DESCRIPTION 🔥

so here's the tea: on FLR, this function will reset all event data related to the VF. all of it. wiped. fresh start, no cap 🌈

and this one is for PF only — like, only the Physical Function gets to call this. don't come at it from anywhere else, iykyk 👑
