In some firmware configuration, UMR usage from Virtual Functions is restricted. This information is published to the driver using new capability bits. Avoid using UMRs in these cases and use the Firmware slow-path flow to create mkeys and populate them with Virtual to Physical address translation. Older drivers that do not have this patch, will end up using memory keys that aren't populated with Virtual to Physical address translation that is done part of the UMR work.
