[libvirt PATCH v8 1/3] Set VF MAC and VLAN ID in two different operations

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

 



This has a benefit of being able to handle error codes for those
operations separately which is useful when drivers allow setting a MAC
address but do not allow setting a VLAN (which is the case with some
SmartNIC DPUs).
