vmxnet3: Report the Device Serial Number capability
Report the DSN extended PCI capability at 0x100. DSN value is a transformation of device MAC address, as calculated by VMware virtual hardware. DSN is reported only if device is pcie. Signed-off-by: Shmulik Ladkani <shmulik.ladkani@ravellosystems.com> Signed-off-by: Jason Wang <jasowang@redhat.com>
