Hi all,

When SR-IOV introduce in Juno the SR-IOV Agent supported only link state change.
Some Intel cards don't support setting link state, so to
resolve it the  SR-IOV mechanism driver supports agent and agent less mode.
>From Liberty the SR-IOV agent brings more functionality like
qos and port security so we want to make the agent mandatory.

I have already talked to pczesno from Intel and got his approval in the pci meeting [1]

For this to happen commit [2] and [3] need to be approved.

If anyone objects to this change now is the time to speak.
