## Overview

In the Linux kernel, the following vulnerability has been resolved:

net: hns3: don't auto enable misc vector

Currently, there is a time window between misc irq enabled
and service task inited. If an interrupte is reported at
this time, it will cause warning like below:

[   16.324639] Call trace:

So don't auto enable misc vector when request irq..
