📦 version 7.3.1, in nixpkgs unstable

💖 ixgbe_fcoe_get_wwn(9) 💖

okay bestie, welcome to the ixgbe_fcoe_get_wwn page from the Kernel API Manual, section 9 — yes section 9, the fun one 🎀. this is the glow-up of the man page, same facts, way more vibe. let's get into it ✨

🦋 NAME 🦋

ixgbe_fcoe_get_wwn — grabs the world wide name for the node or the port, no big deal 💅

✨ SYNOPSIS ✨

int ixgbe_fcoe_get_wwn (struct net_device *netdev , u64 *wwn , int type
);

like, that's the whole signature, keep it exactly like that 🫶

🌸 ARGUMENTS 🌸

  • netdev — the ixgbe adapter, main character energy obviously 👑
  • wwn — the world wide name itself 💫
  • type — which kind of world wide name you're asking for, iykyk

💜 DESCRIPTION 💜

so here's the tea: it returns the node or port world wide name — but only if both the prefix and the san mac address are valid ✅. when that checks out, the wwn gets formed based on the NAA-2 for IEEE Extended name identifier (ref. to T10 FC-LS Spec., Sec. 15.3). literally the spec said so, and we respect the spec 🧚

ngl, if the prefix or the san mac address isn't valid, you're just not getting a wwn formed — that's the whole condition, no cap 🙈

⭐ RETURN ⭐

0 on success 🎉 that's it, that's the return. slay.
