Subject: [dpdk-dev] [PATCH v2] net/i40e: fix VF/PF port reset
Date: Wed, 5 Dec 2018 12:46:25 +0000 [thread overview]
Message-ID: <20181205124625.24398-1-zhirun.yan@intel.com> (raw)
Port reset will call i40evf_uninit_vf() to release resource. It wants
to call i40evf_dev_close() to do some clean work. Before this patch,
port reset will never call i40evf_dev_close() to shutdown adminq. So
the i40evf_dev_init() will failed.
The status of stop/start should be flaged by dev->data->dev_started.
Close should be flaged by hw->adapter_stopped. This patch modify
these flags both in VF and PF.
