✨ __libeth_xdp_set_features(9) ✨

okay so bestie, welcome to the kernel API manual 💖 this one's a lil function called __libeth_xdp_set_features and it's literally all about turning on XDP features for a netdev. buckle up, it's short but it matters.

---

🌸 NAME 🌸

__libeth_xdp_set_features — set XDP features for netdev ✨

---

🎀 SYNOPSIS 🎀

void __libeth_xdp_set_features (struct net_device *dev , const struct
xdp_metadata_ops *xmo , u32 zc_segs , const struct xsk_tx_metadata_ops
*tmo );

---

💅 ARGUMENTS 💅

• dev — the net_device you're configuring, periodt. this is the one that actually matters, no cap.
• xmo — the XDP metadata ops (aka the Rx hints 👀).
• zc_segs — the maximum number of S/G frags the HW can transmit. yeah, hardware limits, iconic of it honestly.
• tmo — the XSk Tx metadata ops (the Tx hints ✨).

---

🦋 DESCRIPTION 🦋

so what does it do? it sets all the features that libeth_xdp supports. that's the whole vibe ✨

here's the tea though: only the first argument is necessary 🫶. and if you don't pass that third one — like, you leave it at zero — then XSk support just won't be advertised. not a bug, just how she works 💀.

⚠️ real talk: use the non-underscored versions in drivers instead. this underscore girlie is the internal one, iykyk 🙈
