From fe5fcefc9130ce80cda024ab44c7353a67df5cb6 Mon Sep 17 00:00:00 2001 From: Liu Shixin Date: Wed, 9 Jun 2021 16:56:49 +0800 Subject: [PATCH] staging: rtl8188eu: Use is_{zero/broadcast}_ether_addr() instead of memcmp() Simplify the code by using is_{zero/broadcast}_ether_addr() instead of directly using memcmp() to determine if the ethernet address is all zeros or broadcast address.
