Description of problem:

VF properties (such as vlan, spoof check, link state etc) are defined in net-attach-def and applied to VF when it's moved to container namespace by SR-IOV CNI. In case no values are specified in net-attach-def for VF properties, SR-IOV CNI won't configure it when cmdAdd is invoked but always restore to a 'default' value when cmdDel is called. The 'default' value for spoof check is 'on'

This causes problem for Mellanox VF as it has a different default value `off`.
The subsequencial use of the same VF (with spoofChk set to on) will block traffic from going out of container via SR-IOV VF.
