ixgbe_set_in...t_capability(9)

💅 NAME 💅

ok so this is the manual page for ixgbe_set_interrupt_capability — and what it does is literally set MSI-X or MSI if the hardware supports it. that's the whole vibe. bestie it's giving "make the interrupts fancy if we can" ✨

this one lives in the Kernel API Manual, section 9, and the full title in the header is ixgbe_set_in...t_capability(9) (yes it's truncated, that's just how the header rolls, don't come for me 🫶).

---

✨ SYNOPSIS ✨

void ixgbe_set_interrupt_capability (struct ixgbe_adapter *adapter );

that's it. that's the whole call. no return value, it's a void — it just goes and does the thing 🔥

---

🎀 ARGUMENTS 🎀

• adapter — this is the board private structure you're initializing. like, the little home base for this board's info, and you're handing it over so it can get set up 💖

---

🌸 DESCRIPTION 🌸

okay so here's the tea: this function attempts to configure the interrupts using the best available capabilities of both the hardware and the kernel. key word attempts — it's out here trying the nicest option first, based on what the hardware can do and what the kernel can do, and that's the whole job 💅

no cap, that's the entire description. short and iconic. periodt.

if you wanna go read the source (and honestly, mood), it's chilling in the kernel file:

and here's the whole friend group — the other functions you probably wanna vibe-check while you're here 👑:

like, that's sixteen whole functions. a whole squad. go read them, iykyk 🧚

lowkey the source path in the footer got cut off too — it's ./drivers/net/ethernet/intel/i... — but you get the idea bestie 😭

okay bye ily, this page is from October 2026, source path ./drivers/net/ethernet/intel/i..., and it's ixgbe_set_in...t_capability(9) all over again at the bottom because manpages love a little symmetry 🎀💜 slay!
