+Description: Allows the user to enable the PCIe traffic generator which
+ will create write TLPs frames - from the Root Complex to the
+ Endpoint direction.
+ Usage e.g.
+ echo 1 > /sys/class/misc/dw-xdata-pcie.<device>/write
+
+ The user can read the current PCIe link throughput generated
+ through this generator in MB/s.
+ Usage e.g.
+ cat /sys/class/misc/dw-xdata-pcie.<device>/write
