okay so real talk, this little function lives in the Kernel API Manual and it's lowkey one of those tiny helper besties that just does one thing and does it slayfully ✨

✨ NAME ✨

opa_get_cpi_capmask2 — it hands you back the capmask2 value, pulled straight out of cap_mask2_resp_time inside ib_class_port_info. that's it, that's the whole vibe 🦋

🌸 SYNOPSIS 🌸

u32 opa_get_cpi_capmask2 (struct opa_class_port_info *cpi );

that's the whole signature, no cap — returns a u32, takes one pointer, done 👑

💖 ARGUMENTS 💖

• cpi — a struct opa_class_port_info mad. yes, that's the actual one-liner and honestly? it's giving minimalism icon behavior. you pass in the struct, it's the mad in question, and we move on 🫶
