[v2,2/3] app/testpmd: add the explicit check for tunnel TSO offload
Checks
Commit Message
If port don't support TSO of tunnel packets, tell user in advance and
no need to change other configuration of this port in case of fault spread.
In addition, if some tunnel offloads don't support, which is not an error
case, the log about this shouldn't be to stderr.
Fixes: 3926dd2b6668 ("app/testpmd: enforce offload capabilities check")
