This is a very good step in the right direction
because testpmd is a tool app.
So testpmd must not enable anything without explicit user request.
The next step will be to check the offload capabilities
before enabling them.
If a requested capability is not available, it should return
either an error, or a warning.
I want to merge this first patch in 18.02-rc2,
because some drivers (lacking some capabilities) cannot be tested
without explicitly disabling the forced offloads.
