Requements from SRIOV
- group device
for SRIOV, alll VFs belong to same PF share same physical network reachability. so if you want, say, deploy a vlan network, you need choose the right PF's VF, otherwise network does not work for you.
- tracking device alloced to the NIC
networking or other special deive is not as simple as pass though to the VM, there is need more configration. to acheive this, SRIOV must know the device infomation allocation to the specific NIC.
Solution: group the devices
whitlist alias use extra info (k,v) as group defination.
solution: tracking device allocated to alias
use request append infomation to alloced device then find if by (k,v)
