okay so we're in the Kernel API Manual, and today's main character is ib_query_netdev_port 😌✨

🌸 NAME 🌸

ib_query_netdev_port — literally query the port number of a net_device associated with an ibdev. that's the whole vibe 🫶

✨ SYNOPSIS ✨

int ib_query_netdev_port (struct ib_device *ibdev , struct net_device
       *ndev , u32 *port );

🦋 ARGUMENTS 🦋

• ibdev — the IB device, bestie. it's giving "the main one" 💅
• ndev — the network device. yes, that net_device 🎀
• port — the IB port the net_device is connected to. iconic output-param behavior, no cap ✨
