[v3] app/testpmd: support the query of link flow ctrl info
Checks
Commit Message
From: Huisong Li <lihuisong@huawei.com>
This patch supports the query of the link flow control parameter
on a port.
The command format is as follows:
show port <port_id> flow_ctrl

v3:
* fixed the print format of link flow ctrl, and removes redundant
port number verification.
v2:
* fixed logging.
