Hi Christophe,
Another issue may relate to driver interface. As you know, there is some
soc level initialization specific to some platform before the network
driver works.
Where do you expect this kind of initialization? at the odp_init or
driver_init? For dpaa2, the thread is also needed before the driver is
working.
thanks,
Forrest
