CVE-2021-47139

In the Linux kernel, the following vulnerability has been resolved: net: hns3: put off calling register_netdev() until client initialize complete Currently, the netdevice is registered before client initializing complete. So there is a timewindow between netdevice available and usable. In this case, if user try to change the channel number or ring param, it may cause the hns3_set_rx_cpu_rmap() being called twice, and report bug.
