ixgbe_cache_ring_sriov(9)

💖 ixgbe_cache_ring_sriov(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ this one's a lil function from the ixgbe driver family, and honestly? she's short but she matters. let's get into it 🫶

---

🌸 NAME 🌸

ixgbe_cache_ring_sriov — literally the descriptor ring to register mapping for sriov 💅 that's the whole vibe. descriptor ring → register mapping, but make it SR-IOV.

---

🦋 SYNOPSIS 🦋

bool ixgbe_cache_ring_sriov (struct ixgbe_adapter *adapter );

that's it. that's the whole call. returns a bool, takes one pointer, no cap 🧚

---

🎀 ARGUMENTS 🎀

• adapter — the board private structure to initialize. like, this is the struct ixgbe_adapter * you're handing over so she can do her thing ✨ it's giving "here's my stuff, go set it up."

---

💜 DESCRIPTION 💜

okay so here's the tea ☕ — SR-IOV doesn't use any descriptor rings. like, at all. none. zero. not a single ring bestie 😭

BUT (and this is the iconic part 👑) it still changes the default if no other mapping is used. so even though there are no rings to map, she's out here making sure the default doesn't just sit there being wrong. main character energy fr fr 💅
