🦋 qed_llh_add_protocol_filter(9) — Kernel API Manual, bestie 🦋

Okay so this is the manual page for qed_llh_add_protocol_filter(9) from the Kernel API Manual. Vibe check: it adds a LLH protocol filter into the given filter bank. Slay. Not me being obsessed with a kernel API, but here we are. 💅

✨ NAME ✨

qed_llh_add_protocol_filter — Add a LLH protocol filter into the given filter bank. That's the assignment, and it ate. 🔥

🌸 SYNOPSIS 🌸

int qed_llh_add_protocol_filter (struct qed_dev *cdev , u8 ppfid , enum qed_llh_prot_filter_type_t type , u16 source_port_or_eth_type , u16 dest_port );

No cap, that's the whole signature. Return type is int, and the arguments are giving very specific main character energy below. 🎀

🎀 ARGUMENTS 🎀

• cdev — Qed dev pointer. Your qed device handle, bestie.
• ppfid — Relative within the allocated ppfids ('0' is the default one). So yes, that '0' is the default one — iconic.
• type — Type of filters and comparing. It's the filter/comparing type, iykyk.
• source_port_or_eth_type — Source port or ethertype to add.
• dest_port — Destination port to add.

💖 RETURN 💖

Int.

Literally just int. No secret extra lore, no dramatic plot twist. Periodt. 😭
