From: Huisong Li <lihuis...@huawei.com>
Currently, to check whether the configured link_speeds is valid, we
have to run "port start". In addition, if the configuration fails,
"port->dev_conf.link_speeds" maintained in testpmd cannot be
restored.
This patch adds the link_speeds check before port start by calling
dev_configure, and resolves these problems.
