💅 ice_fltr_prepare_vlan(9) — from the Kernel API Manual, bestie 🎀

okay so picture this: you're deep in the Intel ice driver, and you need to add or remove a VLAN filter. that's literally it. that's the whole vibe of ice_fltr_prepare_vlan — add or remove VLAN filter. it's giving "small function, big responsibility" ngl. ✨

✨ SYNOPSIS ✨

int ice_fltr_prepare_vlan (struct ice_vsi *vsi , struct ice_vlan *vlan ,
int (*vlan_action)(struct ice_vsi *, struct list_head *) );

yes queen, that's a function pointer in the parameter list. we love a callback moment. 👑

🫶 ARGUMENTS 🫶

• vsi — pointer to VSI struct. it's the VSI, bestie. everything happens in it.
• vlan — VLAN filter details. all the deets for the VLAN filter live here. 🍓
• vlan_action — pointer to add or remove VLAN function. you hand it the actual function that does the adding-or-removing, and it does its thing. main character energy fr fr. 🔥
