[dpdk-dev] [PATCH] usertools: fix device binding when using with kernel tools

[Thomas Monjalon]

26/04/2017 15:52, Guduri Prathyusha:
> The following sequence of operation gives error in binding devices
> 1) Bind a device using dpdk-devbind.py
> 2) Unbind the device using kernel tools(/sys/bus/pci/device/driver/unbind)
> 3) Bind the device using kernel tools(/sys/bus/pci/driver/new_id and
> /sys/bus/pci/driver/bind)
> 
> The bind failure was due to cached driver name in 'driver_override'.
> Fix it by writing 'null' to driver_override just after binding a
> device so that any method of binding/unbinding can be used.
> 
> Fixes: 2fc350293570 ("usertools: use optimized driver override scheme to bind")
