do you mean ip link on the pf shows link state down for the vf?

where do you see it is disabled and what happens if you take the PF
netdev link up?
We had a bug fix there recently [1] -- but it was for the switchdev
mode not the legacy mode, are you
using the switchdev mode? (if not, I recommend going there, the legacy
mode is not going to last long)
Also, FWIW the whole ethernet sriov upstreaming is done in netdev, not rdma
Or.
