[dpdk-dev] [PATCH 1/3] rawdev: allow calling info function for unknown rawdevs

[Thomas Monjalon]

> To call the rte_rawdev_info_get() function, the user currently has to know
> the underlying type of the device in order to pass an appropriate structure
> or buffer as the dev_private pointer in the info structure. By allowing a
> NULL value for this field, we can skip getting the device-specific info and
> just return the generic info - including the device name and driver, which
> can be used to determine the device type - to the user.
> 
> This ensures that basic info can be get for all rawdevs, without knowing
> the type, and even if the info driver API call has not been implemented for
> the device.

This is a new feature. Why should it be backported?
