i think the only caution here is that some of the new names may be
truncated where the valuable information is lost in the truncation?

#define RTE_MAX_THREAD_NAME_LEN 16

a limit inherited from linux and adopted as the dpdk standard/maximum.
by prefixing dpdk- we end up with a bit less name length budget to spend
potentially causing the most important part of the thread name to be lost.

a couple of notes though.
  * some of the existing names may already suffer from truncation. i
    didn't check but can see some that look close.
  * some of your new names have reduced the length so they are in fact
    better.
