Thank you for the post. Will need to look into this.
What a nice support community!
After 2 months no response, it is just a shame for such a community.
The only solution you have given our company is simple: "NEVER BUY FROM INTEL".
and we do: will never ever buy from Intel with such a poor support.
I apologize for any delay and inconvenience this might have caused. Further checking, in order to enable PFC on X710, you need to disable LLDP agent in the adapter firmware and augment the driver, however currently we have no plan to do this.
