👑 ice_add_tc_fltr(9) 👑

okay bestie, welcome to the Kernel API Manual entry for ice_add_tc_fltr(9). we're doing TC flower filter stuff, and yes, it's giving kernel networking main character energy. 💅✨

🌸 NAME 🌸

ice_add_tc_fltr — adds a TC flower filter

🦋 SYNOPSIS 🦋

int ice_add_tc_fltr (struct net_device *netdev , struct ice_vsi *vsi ,
struct flow_cls_offload *f , struct ice_tc_flower_fltr **__fltr , bool
ingress );

🎀 ARGUMENTS 🎀

• netdev — Pointer to netdev. literally a pointer to the netdev, no cap. 🫶
• vsi — Pointer to VSI. yep, pointer to VSI. ✨
• f — Pointer to flower offload structure. 🌸
• __fltr — Pointer to struct ice_tc_flower_fltr. 🎀
• ingress — if the rule is added to an ingress block. 💅

🔥 DESCRIPTION 🔥

This function parses TC-flower input fields, parses action, and adds a filter. that's the whole vibe: parse the fields, parse the action, add the filter. periodt. ✨

💖 RETURN 💖

0 if the filter was successfully added, negative error code otherwise. so if you get 0, slay; if it's negative, that's the kernel saying "not today" 😭💀
