Hello Ma,lihong,

While I was re-testing the entire suite to get the test log file for you, I found a few more issues that occur when running the entire test suite at once. I've included fixes for these but apparently checkpatch doesn't like something about the patch, so I'll resubmit. Sorry about that. I've included the log file after stripping some of the output. Due to how the test was constructed, I wasn't able to use the normal method to run scapy and had to do it through send_expect, which means that all of the colorings in the shell were logged. I've done my best to remove all of the lines with color symbols in them since they aren't needed to understand the output. 

Sorry about messing up the submission again,
Owen

added missing quote in template for scapy packets.
rearraged closing down scapy and testpmd to avoid issues with other test
cases.
