Upstream source description

In the Linux kernel, the following vulnerability has been resolved: net: hns3: fix kernel crash when 1588 is sent on HIP08 devices Currently, HIP08 devices does not register the ptp devices, so the hdev->ptp is NULL. But the tx process would still try to set hardware time stamp info with SKBTX_HW_TSTAMP flag and cause a kernel crash.
