[dpdk-dev] [PATCH v2 07/20] testpmd: move csum_show in a function

[Olivier Matz <olivier.matz@6wind.com>]

No functional changes in this commit, we just move the code
that displays the csum forward engine configuration in a
function.

This makes the next commit easier to read as it will also
use this function.
