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

net: hns3: fix deadlock issue when externel_lb and reset are executed together

When externel_lb and reset are executed together, a deadlock may
occur:

In externel_lb process, the hns3 driver call napi_disable()
first, then the reset happen, then the restore process of the
externel_lb will fail, and will not call napi_enable(). When
doing externel_lb again, napi_disable() will be double call,
cause a deadlock of rtnl_lock().

This patch use the HNS3_NIC_STATE_DOWN state to protect the
calling of napi_disable() and napi_enable() in externel_lb
process, just as the usage in ndo_stop() and ndo_start().
