Hi Chaoyong,

Similar comment with previous versions, interface is created using 
regular 'rte_eth_dev_allocate()' API, I think interface will be visible 
to application, I can't understand the need of creating an interface for 
control.

What is the communication method between driver and FW?
Since one of the following patches (09/12) introduces Rx/Tx for ctrl 
interface, is device interface is control packets (similar to network 
data packets)?
