`strncpy` is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.
We can see that netdev->name is expected to be NUL-terminated based on
it's usage with format strings:
| pr_info("%s NIC Link is Down\n",
| netdev->name);
A suitable replacement is `strscpy` [2] due to the fact that it
guarantees NUL-termination on the destination buffer without
unnecessarily NUL-padding.
This is in line with other uses of strscpy on netdev->name:
$ rg "strscpy\(netdev\->name.*pci.*"
drivers/net/ethernet/intel/e1000e/netdev.c
7455: strscpy(netdev->name, pci_name(pdev), sizeof(netdev->name));
drivers/net/ethernet/intel/ixgbe/ixgbe_main.c
10839: strscpy(netdev->name, pci_name(pdev), sizeof(netdev->name));
