[dpdk-dev] [PATCH v5 4/6] ethdev: adjust APIs removal error report
Matan Azrad
matan at mellanox.com
Wed Jan 17 21:19:15 CET 2018
rte_eth_dev_is_removed API was added to detect a device removal
synchronously.
When a device removal occurs during control command execution, many
different errors can be reported to the user.
Adjust all ethdev APIs error reports to return -EIO in case of device
removal using rte_eth_dev_is_removed API.
