bnx2x_fcoe_get_wwn(9)

📦 version 7.3.1, in nixpkgs unstable

💅 bnx2x_fcoe_get_wwn — the Kernel API Manual, but make it make sense

okay so bestie, this one's from the Kernel API Manual and honestly it's a tiny little function that just wants to hand you a WWN. that's it. that's the whole vibe. it returns the requested WWN value for this port, and we're gonna go through it together, no cap 🎀

✨ NAME ✨

bnx2x_fcoe_get_wwn — return the requested WWN value for this port

like, you ask it for a WWN, it gives you the WWN. iconic behavior honestly 🦋

🌸 SYNOPSIS 🌸

int bnx2x_fcoe_get_wwn (struct net_device *dev , u64 *wwn , int type );

three things go in, an int comes out. it's giving very "simple function, minding its own business" ✨

💖 ARGUMENTS 💖

  • dev — net_device. yes, that's the entire description. the docs said what they said, and what they said was "net_device." we love a low-effort king 👑
  • wwn — output buffer. this is where the answer lands, so like… give it somewhere to live, bestie. it's an output, not an input, so don't go in expecting it to already have your answer in it 🙈
  • type — WWN type: NETDEV_FCOE_WWNN (node) or NETDEV_FCOE_WWPN (port). so you're either asking for the node flavor or the port flavor. pick your fighter, there's only these two 💅
lowkey the whole point: you say which kind of WWN you want (NETDEV_FCOE_WWNN for node, NETDEV_FCOE_WWPN for port) and this thing goes and gets it for you. that's the plot 🍓
