This cause a icc build error:
.../drivers/net/enic/enic_clsf.c(77):
error #188: enumerated type mixed with another type
        info->mode = enic->fdir.modes;
                   ^

Just casting to the enum fixes it:
+       info->mode = (enum rte_fdir_mode)enic->fdir.modes;

Since the modification is trivial, if you agree with the change, we can
apply it without needing a new version of the patch?
