+What:		/sys/bus/pci/drivers/dw-xdata-pcie/.../write
+Date:		February 2021
+KernelVersion:	5.12
+Contact:	Gustavo Pimentel <gustavo.pimentel@synopsys.com>
+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/bus/pci/drivers/dw-xdata-pcie/.../write
+
+		The user can read the current PCIe link throughput generated
+		through this generator in MB/s.
+		Usage e.g.
+		 cat /sys/bus/pci/drivers/dw-xdata-pcie/.../write
+		 204
+
+		The file is read and write.
