ib_device_set_netdev(9)

🌸 NAME 🌸

okay so bestie, welcome to ib_device_set_netdev(9) — yes, the Kernel API Manual page for ib_device_set_netdev ✨ — and it's literally about associating the ib_dev with an underlying net_device. 🫶

✨ SYNOPSIS ✨

int ib_device_set_netdev (struct ib_device *ib_dev , struct net_device *ndev , u32 port );

🎀 ARGUMENTS 🎀

• ib_dev — the device to modify 👑
• ndev — the net_device to affiliate, and it may be NULL 🫶
• port — the IB port the net_device is connected to 🔌

🦋 DESCRIPTION 🦋

Drivers should use this to link the ib_device to a netdev so the netdev shows up in interfaces like ib_enum_roce_netdev. ✨ Only one netdev may be affiliated with any port. periodt.

⚠️ caller responsibility check: the caller must ensure that the given ndev is not unregistered or unregistering, and that either the ib_device is unregistered or ib_device_set_netdev is called with NULL when the ndev sends a NETDEV_UNREGISTER event. 😭 this is not a drill, bestie.
