This patch creates two new helper functions, nxm_reg_load() and nxm_dst_check(). The new nxm_dst_check() function may be used to check the validity of destination fields used by actions. The new nxm_reg_load() function may be used by actions which need to write to NXM fields. This patch also allows multipath and autopath to write their result to non-register NXM fields.
