parse_capability(9)

💅 parse_capability(9) — a Kernel API Manual moment

okay so bestie, welcome to the Kernel API Manual, and the vibe today is glow-ups: this little function's whole job is taking the capability tea the firmware spilled and translating it into NIC capabilities. literally a makeover montage in C. 💖

---

✨ NAME ✨

parse_capability — converts device capabilities into NIC capabilities. it's giving translator, it's giving intermediary, it's giving "let me rephrase that for you bestie." 🦋

---

🌸 SYNOPSIS 🌸

int parse_capability (struct hinic_hwdev *hwdev , struct hinic_dev_cap
*dev_cap );

---

🎀 ARGUMENTS 🎀

• hwdev — the HW device you're setting and converting device capabilities for. it's the main character here, the one getting the glow-up. 👑
• dev_cap — device capabilities straight from FW. the raw material, the before photo, the unedited draft. 🙈

---

💅 DESCRIPTION 💅

Returns 0 for Success, and a negative value for Failure. that's it, that's the whole description, no cap. slay a concise legend. ✨

lowkey love a function that says exactly what it means and dips. no notes. 💀
