idpf_add_mac_filter(9)

🎀 NAME 🎀

okay so bestie, this is idpf_add_mac_filter(9), and we’re in the Kernel API Manual ✨ The whole point is literally Add a mac filter to the filter list — that’s the name, that’s the vibe, it ate. 💅

✨ SYNOPSIS ✨

the signature is giving “kernel function realness,” so keep it exactly like this:

int idpf_add_mac_filter (struct idpf_vport *vport , struct
       idpf_netdev_priv *np , const u8 *macaddr , bool async );

🫶 ARGUMENTS 🫶

• vport — Main vport structure. the main-character struct, no cap.
• np — Netdev private structure. private like a finsta, but for netdev.
• macaddr — The MAC address. the MAC address, literally the moment.
• async — Don't wait for return message. lowkey “I’ll check the group chat later” energy.

💅 DESCRIPTION 💅

Returns 0 on success or error on failure — periodt. If interface is up, we’ll also send the virtchnl message to tell hardware about the filter. that’s the tea, bestie: success gets 0, failure gets an error, and when the interface is up the hardware gets the virtchnl memo about the filter. 🫶
