There was ongoing discussion in TB that the regexdev PMD should
be deprecated and removed. It turns out that HW regex is slower
than software.
It is good to have a software alternative, but going through
DPDK API's to do regex seems like an awkward way to do it.
For applications simpler/faster to use regex libraries directly.
