ice_setup_vf_trust(9)

💅 ice_setup_vf_trust(9) — the group-chat recap

okay so bestie, welcome to ice_setup_vf_trust(9), a genuinely tiny little kernel function from the ice driver that flips VF trust mode on or off without doing a whole reset. it's giving "small but powerful," no cap. let's get into it ✨

---

🌸 SYNOPSIS 🌸

void ice_setup_vf_trust (struct ice_vf *vf , bool setting );

that's it. that's the whole signature. she's short, she's sweet, she returns nothing (void), and she takes exactly two things. periodt 💅

---

🎀 ARGUMENTS 🎀

• vf — the VF you're configuring. like, the actual virtual function you're messing with. that's her.
• setting — the trust setting. the bool. yes/no, on/off, trusted/not-trusted. icon behavior 🫶

---

🦋 DESCRIPTION 🦋

so here's the vibe: this function updates the VF flags when you're changing trust without performing a VF reset. that's the whole magic trick — no reset, just a flag refresh ✨

and like… it is only called when it's safe to skip the reset. specifically: when the VF has no advanced features configured that need cleanup. so if your VF is out here with advanced features needing cleanup, this is not the function for you, bestie. don't come for her. this is the "everything's chill, just update the flags" path 💖

lowkey important: the "safe to skip the reset" part isn't a suggestion, it's the actual precondition. iykyk 🌈
