[dts] Clarifications on setting up DUT

[Ravi Kerur <rkerur@gmail.com>]

DTS team,

I am making changes to DTS to support i217, i218 chipsets to DTS and I have
couple of questions

1. Any README on system pre-requisites? Can I run DTS natively on DUT
without any SSH?

 I have I217 and 82540EM NICs in a system running Ubuntu. I would like to
use both NIC's for testing. If I use regular method of SSH, I will loose
one NIC hence the question.

2. When I run DTS, for some of the commands I am getting garbage output.
The problem is seen on 2 Ubuntu systems. When I run those commands manually
commands work fine for e.g.

*16/01/2015 12:58:00       DTS_TESTER_CMD: ls
/sys/bus/pci/devices/0000:00:19.0/net*

*16/01/2015 12:58:00    DTS_TESTER_OUTPUT: ^[[0m^[[01;34meth0^[[0m*

*16/01/2015 12:58:00       DTS_TESTER_CMD: Tester: [000:00:19.0 8086:15a1]
^[[0m^[[01;34meth0^[[0m*

*16/01/2015 12:58:00       DTS_TESTER_CMD: cat
/sys/bus/pci/devices/0000:00:19.0/net/^[[0m^[[01;34meth0^[[0m/address*

*16/01/2015 12:58:00    DTS_TESTER_OUTPUT: cat:
/sys/bus/pci/devices/0000:00:19.0/net/m1: No such file or directory^M*

*-bash: 34meth0m/address: No such file or directory*

*16/01/2015 12:58:00       DTS_TESTER_CMD: ls
/sys/bus/pci/devices/0000:04:02.0/net*

*16/01/2015 12:58:00    DTS_TESTER_OUTPUT: ^[[0m^[[01;34meth1^[[0m*

*16/01/2015 12:58:00       DTS_TESTER_CMD: Tester: [000:04:02.0 8086:100e]
^[[0m^[[01;34meth1^[[0m*

*16/01/2015 12:58:00       DTS_TESTER_CMD: cat
/sys/bus/pci/devices/0000:04:02.0/net/^[[0m^[[01;34meth1^[[0m/address*


3. Tests start failing with following msgs even though I217 NIC is
recognized.

*Traceback (most recent call last):*

*  File "/home/rkerur/dpdk-dts/dts/framework/dts.py", line 527, in
