okay so bestie, welcome to ksz9477_cls_flower_del(9) ✨ like yes the title is a whole mouthful but it's literally just "the function that deletes a flow classification rule for one specific port on a ksz_device." she's the cleanup crew, she's the one who shows up after the party and takes the decorations down 🎀

🌸 NAME 🌸

ksz9477_cls_flower_del — remove a flow classification rule for a specified port on a ksz_device. no cap, that's the whole job description 💅

---

✨ SYNOPSIS ✨

int ksz9477_cls_flower_del (struct dsa_switch *ds , int port , struct
flow_cls_offload *cls , bool ingress );

like look at her signature, she's giving very "four parameters, zero drama" 🦋 (well, some drama — see RETURN below 😭)

---

🫶 ARGUMENTS 🫶

• ds — The DSA switch instance. this is the switch itself, the main character 👑
• port — The port number to remove the flow classification rule from. yes, the specific port, not all of them, we are targeted here 💖
• cls — The flow_cls_offload instance containing the flow rule. she's carrying the rule, treat her with respect 🧚
• ingress — A flag indicating if the rule is applied on the ingress path. ingress girlies rise up 🌈

💀 DESCRIPTION 💀

okay so here's the vibe check: this function removes a flow classification rule for a specified port on a ksz_device. simple as that, lowkey 🌸

but first — and this is the important part — she checks if the ACL is initialized. and if it is not initialized? she returns an error. periodt. no ACL, no service 🙈

if the ACL is initialized, she removes entries with the specified cookie and rewrites the ACL list. so she's not just deleting, she's doing a whole little renovation afterwards, iconic behavior honestly ✨🔥

---

⭐ RETURN ⭐

0 on success or a negative error code on failure. that's it, that's the whole fortune cookie 🍓 (negative numbers are never a slay, but at least you know what happened 💀)
