[dts] [patch V1 1/2] add fdir test case

[Liu, Yong]

Huilong,
Some overall comments.
1. Fdir command is very complicated and has lots of parameters. We need some basic description for these commands. It will help user known what will happened after input fdir commands.
2. To make the plan more clear, do not combine two or three testpmd commands in one line.

Thanks,
Marvin

Please separate into different lines, it's hard to read when combined several commands to one line.

Please add some basic description for these commands, like what's the meaning of internal bytes.
As I known, "raw" layer also supported by flow director flex bytes. Should cover this layer too?

Please align the output, prefix "testpmd>" should start on second line.
