Where are the MLX5_CAP_UMR defines declared? Am I missing something?
What is the value of MLX5_CAP_UMR_FENCE_NONE? if its zero then this
change is not backwards compatible with older FW.
they are declared in patch 1/2:
+enum {
+ MLX5_CAP_UMR_FENCE_STRONG = 0x0,
+ MLX5_CAP_UMR_FENCE_SMALL = 0x1,
+ MLX5_CAP_UMR_FENCE_NONE = 0x2,
+};

Thanks,
Max.
