[dpdk-dev] [PATCH] app/testpmd: add flow isolate all parameter

[Vasily Philipov <vasilyf@mellanox.com>]

Providing this parameter requests flow API isolated mode on all ports at
initialization time. It ensures all traffic is received through the
configured flow rules only (see flow command).

Ports that do not support this mode are automatically discarded.
