-Subject: [PATCH 12/20] haswell NRI: Add function to change margins
-
-Implement a function to change margin parameters. Haswell provides a
-register to apply an offset to margin parameters during training, so
-make use of it. There are other margin parameters that have not been
-implemented yet, as they are not needed for now and special handling
-is needed to provide offset training functionality.
