rdma_core_cap_opa_port(9)

🌸 NAME 🌸

okay so bestie, welcome to the Kernel API Manual page for rdma_core_cap_opa_port(9) 💖 — and the function is literally rdma_core_cap_opa_port — Return whether the RDMA Port is OPA or not. that’s the whole assignment, no cap. 💅

✨ SYNOPSIS ✨

bool rdma_core_cap_opa_port (struct ib_device *device , u32 port_num );

🎀 ARGUMENTS 🎀

• device — Device. literally the Device you’re checking, bestie. 🫶
• port_num — 1 based Port number. yes, one-based, keep that in mind. 🎀

🦋 DESCRIPTION 🦋

Return true if port is an Intel OPA port, false if not. that’s it — no extra lore, no hidden side quest. ✨
