iavf_find_filter(9)

📦 version 7.3.1, in nixpkgs unstable

💅 iavf_find_filter — the Kernel API Manual, bestie edition ✨

okay so this is iavf_find_filter(9) from the Kernel API Manual, and honestly? it's a little legend. it's the "hey bestie, have u seen this MAC address" of the iavf driver 🦋

🌸 NAME 🌸

iavf_find_filter — lowkey searches the filter list for one specific mac filter 🔍💖

✨ SYNOPSIS ✨

struct iavf_mac_filter * iavf_find_filter (struct iavf_adapter *adapter
, const u8 *macaddr );

like, that's the whole vibe. it hands u back a struct iavf_mac_filter * pointer. periodt. 👑

🎀 ARGUMENTS 🎀

  • adapter — the board private structure. it's giving "main character struct" fr fr, this is where all the driver's private lil secrets live 💅
  • macaddr — the MAC address. yes the. the one ur looking for. the one u want to find. go get her 🐝

💜 DESCRIPTION 💜

okay so it returns a ptr to the filter object — or NULL if it's not giving anything 😭 like if the filter isn't there, u get NULL, no cap.

⚠️ big one, bestie: it must be called while holding the mac_vlan_list_lock. not optional. not "eh maybe later". MUST. lock it first or ur gonna have a bad time 💀🔒

and that's the whole page, bestie 💖 this lil icon came from ./drivers/net/ethernet/intel/iavf, dated October 2026, and it's iavf_find_filter(9) all the way down. now go hold that lock before u call her 🫶🔒✨
