ice_get_vf_from_pfq(9)

okay bestie, welcome to ice_get_vf_from_pfq(9) from the Kernel API Manual — it’s literally the tiny lookup that tells you which VF owns the PF-space queue you passed in. 💅✨

💖 NAME 💖

ice_get_vf_from_pfq — get the VF who owns the PF space queue passed in. That’s the whole vibe: hand over a queue index, get the matching VF. 🎀

✨ SYNOPSIS ✨

struct ice_vf * ice_get_vf_from_pfq (struct ice_pf *pf , u16 pfq );

🧚 ARGUMENTS 🧚

• pf — the PF used to index all VFs. It’s giving “main character list of VFs,” no cap. 👑
• pfq — queue index relative to the PF’s function space. Keep it exact bestie. 🌸

🌸 DESCRIPTION 🌸

so the tea is: if no VF is found who owns the pfq, then return NULL. Otherwise, return a pointer to the VF who owns the pfq. Slay. 💅

⚠️ big important caveat, bestie: if this function returns non-NULL, it acquires a reference count of the VF structure. The caller is responsible for calling ice_put_vf to drop this reference. Do not forget the ice_put_vf, or that reference is gonna be living rent-free. 😭🔥
