[dpdk-dev] [dpdk-stable] [PATCH v2] ethdev: fix invalid length write on dev detach

> The name of a device is copied in a provided buffer within

> The name field of an rte_device is not assured however to point an
> rte_devargs name field. The almost correct length to base this copy over
> is thus RTE_DEV_NAME_MAX_LEN.

> Almost correct, because unfortunately this function does not allow the
> user to pass down a size parameter for the buffer it is meant to write.
> This API should be fixed, it is broken by design.
