[dpdk-dev] [PATCH v2 2/2] app/testpmd: fix link speed for a specified port

["Min Hu (Connor)" <humin29@huawei.com>]

From: Huisong Li <lihuisong@huawei.com>

When we use the following cmd to modify the link speed of specified
port: "port config <port_id> speed xxx duplex xxx", we have to stop
all ports. It's not necessary.

Fixes: 82113036e4e5 ("ethdev: redesign link speed config")
