From 364f4efa444150df3f074f563374dce1e153adc6 Mon Sep 17 00:00:00 2001 From: Zhang Lubo Date: Fri, 8 Apr 2016 09:48:14 +0800 Subject: MdeModulePkg: Add new macros and refine codes Add 2 macros inNetLib.h #define IP4_MASK_MAX 32 #define IP6_PREFIX_MAX 128 we will use these two macros to check the max mask/prefix length, instead of #define IP4_MASK_NUM 33 #define IP6_PREFIX_NUM 129 which means a valid number. This will make the code readability and maintainability.
