Bug Description

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.

Just to confirm. Is that only required for 4.15 kernels?

Yes, this is for DPDK and therefore applies only to 4.15 forward.

Hi, Madhuri. Is this entire PR from comment #1 necessary?

I'm facing a lot of conflicts when trying to apply it to 4.15. The two commits from the initial description apply cleanly though.
