💖 NAME 💖

i40e_devlink_set_switch_id — set a unique switch id based on the pci dsn ✨

okay so bestie, you're on the i40e_devlink_set_switch_id(9) page from the Kernel API Manual, and we're about to make this kernel function make sense 💅

✨ SYNOPSIS ✨

This is the whole signature, no crumbs:

void i40e_devlink_set_switch_id (struct i40e_pf *pf , struct
       netdev_phys_item_id *ppid );

It's void, so no return value is coming back at you — the synopsis said what it said 🫶

🎀 ARGUMENTS 🎀

• pf — the PF to create a devlink port for. That's literally the assignment, bestie 😌
• ppid — struct with switch id information. It's giving "the switch id info lives right here" ✨
