Several things about your patch:
-  It looks like this is your first patch (plus the other one you sent a few minutes later): take a look at http://dpdk.org/dev
- You forgot to sign off your patches (use --signoff with git commit)
- The title of this patch is too long, shorten it and include more information in the body of the commit message.
- I don't know what this patch is trying to solve exactly. It looks like you are saying that there is a bug
  that makes TX stop when you run the following commands:
   testpmd> start
   testpmd> show port info 0

I don't see such bug, could you explain better the steps to reproduce the issue?

Thanks,
Pablo
