set_ppf(9)

💖 NAME 💖

okay so this is set_ppf(9), straight out of the Kernel API Manual, and it's here to explain one tiny but iconic function. set_ppf — try to set hwif as ppf and set the type of hwif in this case. That's the whole assignment, bestie: it tries to set hwif as ppf, and in this case it sets the type of hwif. No cap, “try” is doing real work in that sentence. 💅

✨ SYNOPSIS ✨

The signature is short and sweet, like a text that gets straight to the point:

void set_ppf (struct hinic_hwif *hwif );

It's void, so there's no return value to collect — the function just does its thing. 🫶

🦋 ARGUMENTS 🦋

One argument, and it's the main character:

• hwif — the HW interface of a pci function device. That's the one being passed in.
