ksz9477_flower_parse_key(9)

🌸 NAME 🌸

okay so bestie, this is the ksz9477_flower_parse_key(9) page from the Kernel API Manual, and the whole point is literally to parse flow rule keys for a specified port on a ksz_device. no cap, that's the function's main character job. 💅

---

✨ SYNOPSIS ✨

int ksz9477_flower_parse_key (struct ksz_device *dev , int port , struct
       netlink_ext_ack *extack , struct flow_rule *rule , unsigned long cookie
       , u32 prio );

---

🎀 ARGUMENTS 🎀

• dev — the ksz_device instance. it's giving "the device we're working with," obviously.
• port — the port number to parse the flow rule keys for.
• extack — the netlink extended ACK for reporting errors.
• rule — the flow_rule to parse.
• cookie — the cookie to associate with the entry.
• prio — the priority of the entry.

---

🦋 DESCRIPTION 🦋

okay so here's the vibe check: this function checks if the used keys in the flow rule are supported by the device, and it parses the L2 keys if they match. slay.

🚨 if unsupported keys are used, an error message is set in the extended ACK. so yeah, it does not just ignore the problem — it reports it. periodt.

---

💖 RETURN 💖

0 on success, or a negative error code on failure. simple as that, bestie. 🫶
