[dpdk-dev] [PATCH] eal: remove vdev probe by dev args
Ferruh Yigit

Wed May 10 13:01:04 CEST 2017
Virtual device/driver probing done via name.
A new alternative method introduced to probe the device with providing
driver name in devargs as "driver=<driver_name>".
This patch removes alternative method and fixes virtual device usages
with proper device names.
Fixes: 87c3bf29c642 ("test: do not short-circuit null device creation")
Fixes: d39670086a63 ("eal: parse driver argument before probing drivers")
