[dpdk-dev] [PATCH 2/2] app/testpmd: load cmdline commands from file at runtime

[Allain Legacy]

Adds support to testpmd to load a set of cmdline CLI commands at runtime.
This can be helpful when needing to cut-n-paste many commands where
cut-n-paste may not be practical.

   testpmd> load /home/ubuntu/somefile.txt
