Long explanation:
it's a vOIS bug due to duplex auto negotiation failure, you can do nothing but configure a full duplex every time the device reload.

If I am not wrong, the same issue was with l2 IOL, so, needed to add duplex settings after each reboot

I cant believe we came this far but something simple as duplex mismatch cant be fixed for once and for all.
