Hi,
We are using STX 4.0.1 to install our Flexran based 5G solution in AIO-SX mode . We had created VFs on the N3000 device and some of the NIC interfaces. These resources were reflected in the Kuberenets allocatable resources. During the course of using the system, the allocatable resources for N3000 and one of the NIC interface crad started coming up as 0. The following is a part of kubectl describe nodes output. The affected resources are intel.com/intel_fpga_fec, intel.com/pci_sriov_net_datanet_c, and intel.com/pci_sriov_net_datanet_u
We already tried lock/unlock, delete and re-create the resources, but none of these help to recover the resources

It seems like everything is "OK" upto sriov device plugin because the sriov device plugin pod logs do show that the correct number of resources are getting updated towards kubernetes
Here are some of the CLI outputs:
