[dpdk-dev] [PATCH 3/3] app/testpmd: fix uninitialized members when setting PFC

[Wei Hu (Xavier)]

From: "Wei Hu (Xavier)" <xavier.huwei at huawei.com>

Only a part of members in the local structure variable named pfc_conf are
initialized in the function named cmd_priority_flow_ctrl_set_parsed when
typing "set pfc_ctrl..." command, and others are random values. However,
those uninitialized members may cause failure.

This patch adds clearing zero operation before calling the API named
rte_eth_dev_priority_flow_ctrl_set API with pfc_conf as the input
parameter.
