🦋 gether_connect(9) Kernel API Manual girlie 🦋

okay so bestie, welcome to the gether_connect(9) page from the Kernel API Manual — we're gonna get you comfy with it, no cap. 💖

🌸 NAME 🌸

gether_connect — notify network layer that USB link is active.

✨ SYNOPSIS ✨

struct net_device * gether_connect (struct gether *link );

🎀 ARGUMENTS 🎀

• link — the USB link, set up with endpoints, descriptors matching current device speed, and any framing wrapper(s) set up. 💅

🫶 CONTEXT 🫶

context vibes: irqs blocked. that's it, that's the context. 😌

💖 DESCRIPTION 💖

so this is the call that activates endpoints and lets the network layer know the connection is active ("carrier detect"). yes, it's giving main character energy for your USB link. ✨

It may cause the I/O queues to open and start letting network packets flow, but it will in any case activate the endpoints so that they respond properly to the USB host. basically: packets might start flowing, but the endpoint activation is happening either way — periodt. 🔥

Verify the net_device pointer returned using IS_ERR. If it doesn't indicate some error code (negative errno), then the ep->driver_data values have been overwritten. 😭 so like, check it, bestie — fr fr.
