[7/7] net/iavf: fix port close
Checks
Commit Message
From: "Zhang, RobinX" <robinx.zhang@intel.com>
Port reset will call iavf_dev_uninit() to release resources. It wants
to call iavf_dev_close() to release resources. So there will be a
call conflict if calling iavf_dev_reset() and iavf_dev_close() at the
same time.
This patch added adapter->closed flag in iavf_dev_close()
to control the status of close.
Fixes: 83fe5e80692a ("net/iavf: move device state flag")
