i40e_vsi_free_q_vectors(9)

💖 NAME 💖

i40e_vsi_free_q_vectors — bestie, this one frees the memory that was allocated for the interrupt vectors ✨

🎀 SYNOPSIS 🎀

void i40e_vsi_free_q_vectors (struct i40e_vsi *vsi );

🦋 ARGUMENTS 🦋

• vsi — the VSI that's currently being un-configured, aka the thing we're packing up 💅

🌸 DESCRIPTION 🌸

Okay so real talk: this function frees the memory that was allocated to the q_vectors, and it also deletes the references to the NAPI struct. That's the whole vibe check — memory goes bye-bye, NAPI references get cleaned out. Periodt 🫶
