There is already a command to configure isolate mode per-port:
http://dpdk.org/patch/25320
http://dpdk.org/doc/guides/testpmd_app_ug/testpmd_funcs.html#flow-syntax
I think it does not make sense to replicate this per-port command in
command line parameters.
All the other parameters are global:
http://dpdk.org/doc/guides/testpmd_app_ug/run_app.html#testpmd-command-line-options
The idea here is to have a global isolate mode with a general option.
