Hi Doug,
This patch set adds the functionality to advertise standard atomic operations
capabilities for mlx5 driver. The Hardware can be configured to work in two
modes according to the device capabilities: 1. Big Endian requestor respond 2.
Host Endian requestor respond
If the firmware supports host endianness, try to configure the hardware to work
this way, and on success propagate this capability to the upper layers,
otherwise advertise that atomic operations aren't supported.
Thanks, Eran
