igc_add_mac_filter(9)

Hey bestie 💖 welcome to the igc_add_mac_filter(9) page in the Kernel API Manual — yes, the manual name is right there, we’re not doing the boring header-line copy-paste today.

🌸 NAME 🌸

igc_add_mac_filter — the function that adds a MAC address filter, no cap ✨

✨ SYNOPSIS ✨

int igc_add_mac_filter (struct igc_adapter *adapter , enum igc_mac_filter_type type , const u8 *addr , int queue );

That’s the whole signature, bestie — spacing and all. Don’t let it jump-scare you 💅

🎀 ARGUMENTS 🎀

• adapter — pointer to the adapter where the filter should be added.
• type — the MAC address filter type (source or destination).
• addr — the MAC address.
• queue — if it’s non-negative, the queue assignment feature is enabled and frames matching the filter are enqueued onto 'queue'. Otherwise, queue assignment is disabled.

💖 RETURN 💖

0 in case of success, and a negative errno code otherwise. Success is a zero, not a zero-thoughts moment 🫶
