ice_destroy_all_ctrlq(9)

okay so bestie, welcome to the Kernel API Manual page for ice_destroy_all_ctrlq(9) ✨. This is the exit routine for all control queues, and we're keeping every detail exactly where it belongs, no cap 💖.

✨ NAME ✨

• ice_destroy_all_ctrlq — exit routine for all control queues 💅

🦋 SYNOPSIS 🦋

void ice_destroy_all_ctrlq (struct ice_hw *hw );

🎀 ARGUMENTS 🎀

• hw — pointer to the hardware structure 🫶

💜 DESCRIPTION 💜

This function shuts down all the control queues and then destroys the control queue locks. It should be called once during driver unload — that's its whole main-character moment 🎀.

If the driver needs to shut down and reinitialize control queues — such as in response to a reset event — the driver should call ice_shutdown_all_ctrlq 🔁.

tiny reminder: this one is for driver unload, and it should be called once, okay? 💅
