Date: Wed, 19 Jan 2022 00:54:15 -0500	[thread overview]
Message-ID: <20220119055415.4424-1-wei.huang@intel.com> (raw)

From: Tianfei Zhang <tianfei.zhang@intel.com>

When we want to close a thread, we should set a flag to
thread handler function.

Fixes: 9c006c45 ("raw/ifpga: scan PCIe BDF device tree")
Cc: stable@dpdk.org
