5Description:	Allows the user to enable the PCIe traffic generator which
6		will create write TLPs frames - from the Root Complex to the
7		Endpoint direction or to disable the PCIe traffic generator
8		in all directions.
9
10		Write y/1/on to enable, n/0/off to disable
11
12		Usage e.g.
13		 echo 1 > /sys/class/misc/dw-xdata-pcie.<device>/write
14		or
15		 echo 0 > /sys/class/misc/dw-xdata-pcie.<device>/write
16
17		The user can read the current PCIe link throughput generated
18		through this generator in MB/s.
19
20		Usage e.g.
21		 cat /sys/class/misc/dw-xdata-pcie.<device>/write
22		 204
23
24		The file is read and write.
