From: Huisong Li <lihuis...@huawei.com>
When configuring DCB, testpmd retains the rx_mode/tx_mode configuration in
rte_port->dev_conf. But some configurations, such as the link_speed, were
not saved if it were set before configuring DCB.
Fixes: 1a572499beb6 ("app/testpmd: setup DCB forwarding based on traffic class")
