[PATCH V2 09/12] vDPA/ifcvf: manage ifcvf_hw in the mgmt_dev

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This commit allocates the hw structure in the
management device structure. So the hardware
can be initialized once the management device
is allocated in probe.
