Ivan, what do you think about this flow [1]? Shouldn't it also goto reset_finish label?

	if (i == IAVF_RESET_WAIT_COMPLETE_COUNT) {
		dev_err(&adapter->pdev->dev, "Reset never finished (%x)\n",
			reg_val);
		iavf_disable_vf(adapter);
		mutex_unlock(&adapter->client_lock);
		mutex_unlock(&adapter->crit_lock);
		return; /* Do not attempt to reinit. It's dead, Jim. */
	}

I am concerned that if the reset never finishes and iavf goes into disabled state, and then for example if driver reload operation is performed, bad things can happen.

I think we should not re-attach device back as the VF is disabled. Detached device causes that userspace (user) won't be able to configure associated interface
that is correct. Driver reload won't cause anything special in this situation because during module removal the interface is unregistered.

Thanks,
Ivan
