This patch implements L2 CAT get value interface in domctl. Signed-off-by: Yi Sun <yi.y.sun@linux.intel.com> --- v11: - remove "get_val' assignment because it has been replaced by generic codes. (suggested by Jan Beulich) v10: - remove cast in domctl. (suggested by Jan Beulich) v9: - reuse 'cat_get_val' for L2 CAT to reduce redundant codes (suggested by Roger Pau) - changes about 'uint64_t' to 'uint32_t'. (suggested by Jan Beulich) v5: - remove type check in callback function. (suggested by Jan Beulich) v4: - create this patch because of codes architecture change.
