Hi Leon, David, This patch is not good for the ENA driver as it breaks the interface with the FW of the ENA device in ena_config_host_info(), host_info is later reported to the FW. Please do not merge it yet. We are now working on altering your patch so that it won't break this interface and will send it to you in the next few hours.
