Guidance needed for validating SR-IOV Operator on single-node Kubernetes cluster (Mellanox ConnectX-6 Lx) #968
Description
I am setting up and validating the SR-IOV Network Operator on a single-node Kubernetes cluster on s390x architecture
with Mellanox Technologies MT2894 Family [ConnectX-6 Lx] card
and would like guidance on what tests are recommended, or how validation should be performed in this type of setup.
