Description

net: hns3: fix a deadlock problem when config TC during resetting

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

net: hns3: fix a deadlock problem when config TC during resetting

When config TC during the reset process, may cause a deadlock, the flow is

as below:

pf reset start

│

▼

......

setup tc │

│ ▼

▼ DOWN: napi_disable()

napi_disable()(skip) │

│ │

▼ ▼

...... ......

│ │

▼ │

napi_enable() │

▼

UINIT: netif_napi_del()

│

▼

......

│

▼

INIT: netif_napi_add()

│

▼

...... global reset start

│ │

▼ ▼

UP: napi_enable()(skip) ......

│ │

▼ ▼

...... napi_disable()

In reset process, the driver will DOWN the port and then UINIT, in this

case, the setup tc process will UP the port before UINIT, so cause the

problem. Adds a DOWN process in UINIT to fix it.
