hinic_hwdev_ifup(9)

💅 hinic_hwdev_ifup(9) — the Kernel API Manual page you didn't know you needed

okay so bestie, welcome to hinic_hwdev_ifup(9) from the Kernel API Manual ✨ this one's short but she's important — she's the glow-up your NIC hardware goes through before it's allowed to, like, actually do IO 🫶

---

🌸 NAME 🌸

hinic_hwdev_ifup — Preparing the HW for passing IO 💖 literally bringing the hardware up so the IO can flow, no cap

---

✨ SYNOPSIS ✨

int hinic_hwdev_ifup (struct hinic_hwdev *hwdev , u16 sq_depth , u16
rq_depth );

like, that's the whole signature, copy it exactly bestie 🎀

---

🦋 ARGUMENTS 🦋

• hwdev — the NIC HW device 👑 that's your network interface card's hardware device, the main character
• sq_depth — the send queue depth 📤 how deep the send queue goes
• rq_depth — the receive queue depth 📥 how deep the receive queue goes

---

🌈 DESCRIPTION 🌈

Return 0 - Success, negative - Failure 😭

ngl that's the entire description in the original and we're not gonna invent lore, so: 0 means she ate and it worked, anything negative means it did not work 💀
