idpf_find_mac_filter(9)

💅 idpf_find_mac_filter — Kernel API Manual, section 9 ✨

okay so bestie, welcome to the idpf_find_mac_filter(9) page. This is from the Kernel API Manual, and it is literally giving “find one specific mac filter in a list” energy. Let’s get into it. 🫶

✨ NAME ✨

idpf_find_mac_filter — search the filter list for a specific mac filter. 💅

🎀 SYNOPSIS 🎀

struct idpf_mac_filter * idpf_find_mac_filter (struct idpf_vport_config
       *vconfig , const u8 *macaddr );

🌸 ARGUMENTS 🌸

• vconfig — the Vport config structure. That’s the setup, bestie.
• macaddr — the MAC address. The one we are looking for 👀.

🦋 DESCRIPTION 🦋

This function returns a ptr to the filter object or NULL. No cap.

⚠️ Huge caveat, bestie: it must be called while holding the mac_filter_list_lock. Like, do not skip the lock. This is the “must” of all “musts”. 🔒
