napi_enable(9)

okay bestie, welcome to the Kernel API Manual — this is the napi_enable(9) page, and it’s giving “small function, big responsibility.” Let’s go. 💅

💖 NAME 💖

napi_enable — enable NAPI scheduling ✨

✨ SYNOPSIS ✨

void napi_enable (struct napi_struct *n );

🎀 ARGUMENTS 🎀

• n — NAPI context. That’s the whole vibe check: it’s the NAPI context. 🫶

🦋 DESCRIPTION 🦋

okay so this enables scheduling of a NAPI instance. No cap.

It must be paired with napi_disable — bestie, do not forget the pairing, that’s the rule.

It takes netdev_lock for the associated net_device. 🔥
