✨ nfp_eth_read_ports(9) ✨

okay so bestie, welcome to the Kernel API Manual entry for nfp_eth_read_ports — yes that's the (9) section, we're in kernel-land now, put your seatbelt on 🎀

💖 NAME 💖

nfp_eth_read_ports — retrieve port information 🦋

like, it goes and gets the port info for you. that's the whole vibe.

🌸 SYNOPSIS 🌸

struct nfp_eth_table * nfp_eth_read_ports (struct nfp_cpp *cpp );

🧚 ARGUMENTS 🧚

  • cpp — the NFP CPP handle 🫶 that's your lil ticket into the NFP CPP world, and this function needs it to do literally anything.

👑 DESCRIPTION 👑

So here's the tea ☕: this function reads the port information from the device. That's it. That's the job. It reads it, hands it back to you.

⚠️ important bestie: the returned structure should be freed with kfree once it's no longer needed. not "whenever", not "eh, the kernel will figure it out" — kfree, when you're done. no cap. 💀

⭐ RETURN ⭐

  • a populated ETH table 🔥 — slay, it worked
  • or NULL on error 😭 — it did not work, that's the whole signal
