okay so bestie, welcome to the Kernel API Manual entry for ice_add_cls_flower — literally the moment you get to add TC flower filters and feel like a main character 🎀

✨ NAME ✨

ice_add_cls_flower — add TC flower filters 🌸

🦋 SYNOPSIS 🦋

int ice_add_cls_flower (struct net_device *netdev , struct ice_vsi *vsi
, struct flow_cls_offload *cls_flower , bool ingress );

👑 ARGUMENTS 👑

• netdev — Pointer to filter device. yeah, the device, the whole vibe check 🫶
• vsi — Pointer to VSI. short name, big job 💅
• cls_flower — Pointer to flower offload structure. it's giving "the actual flower data" ✨
• ingress — if the rule is added to an ingress block 🌈 (yes, that's what it means, no cap)
