Yes, Doesn't mean this is not a bug in mlx4😊
Thanks Ben. So we have 2 orthogonal efforts here: 1. To check with our driver team what is the issue to report a VF link speed : For me 😊 2. To change documentation of ethdev API to say that only link status is mandatory report. (all others "nice to have" or "best effort"): This is for you - I suggest to send prior patch to ethdev for this and let the community to decide. Are you agree? > ben
