ice_fltr_prepare_mac(9)

📦 version 7.3.1, in nixpkgs unstable

🌸 NAME 🌸

Okay so bestie, this is the ice_fltr_prepare_mac(9) page from the Kernel API Manual, and it is literally about how to add or remove a MAC rule — that's the whole assignment. MAC rule prep, no cap. 💅✨

✨ SYNOPSIS ✨

Here's the signature, copied exactly because we do not play with code:

int ice_fltr_prepare_mac (struct ice_vsi *vsi , const u8 *mac , enum
       ice_sw_fwd_act_type action , int (*mac_action)(struct ice_vsi *, struct
       list_head *) );

Notice the int return type, the struct ice_vsi *vsi, the const u8 *mac, the enum ice_sw_fwd_act_type action, and the whole function-pointer situation int (*mac_action)(struct ice_vsi *, struct list_head *) — all staying exactly as-is, periodt. 🫶

🎀 ARGUMENTS 🎀

  • vsi — pointer to VSI struct. That's your context bestie, the VSI struct pointer. 💖
  • mac — MAC address to add. The MAC address goes here, and yes it's the one being added. 🦋
  • action — action to be performed on filter match. That's the action vibe for when the filter matches. ⭐
  • mac_action — pointer to add or remove MAC function. It's a function pointer, and it points to the add or remove MAC function — iykyk. 🔥
