ice_get_vf_ctrl_vsi(9)

💅 ice_get_vf_ctrl_vsi — the "where's the other control VSI at" finder 🎀

okay so real talk, this one's from the Kernel API Manual and it's lowkey a little side-quest function in the ice driver. let's get into it bestie ✨

---

🌸 NAME 🌸

ice_get_vf_ctrl_vsi — Get first VF control VSI pointer 👑

---

🦋 SYNOPSIS 🦋

struct ice_vsi * ice_get_vf_ctrl_vsi (struct ice_pf *pf , struct ice_vsi
*vsi );

---

💖 ARGUMENTS 💖

• pf — the PF private structure. like, the whole personality of the physical function fr fr 💅
• vsi — pointer to the VSI. the one you're not looking for, as you're about to find out 👀

---

🔥 DESCRIPTION 🔥

so the vibe is: this function returns the first found VF control VSI other than the vsi passed by parameter. iykyk — you're not getting your own VSI back, you're getting a different one. main character energy but make it a pointer 🌟

the way that this is used? it's genuinely iconic: this function figures out whether new resources have to be allocated for a control VSI, or whether they can just be shared with an existing one. efficient queen behavior honestly 🫶

Return value tea ☕: it returns the found VF control VSI pointer other than itself. otherwise it returns NULL. periodt. 💀
