[dpdk-dev] [PATCH 1/4] app/testpmd: fix missing verification of port id

From: Chengchang Tang <tangchengchang at huawei.com>

To set Tx vlan offloads, it is required to stop port firstly. But before
checking whether the port is stopped, the port id entered by the user
is not checked for validity. When the port id is illegal, it would lead
to a segmentation fault since it attempts to access a member of
non-existent port.

This patch adds verification of port id in tx vlan offloads.

Fixes: 597f9fafe13b ("app/testpmd: convert to new Tx offloads API")
