From a599b0f54d233d0f63d6be9a2ff0049d24751669 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Tue, 8 May 2012 18:56:45 +0000 Subject: [PATCH] etherdevice.h: Add ether_addr_equal Add a boolean function to check if 2 ethernet addresses are the same. This is to avoid any confusion about compare_ether_addr returning an unsigned, and not being able to use the compare_ether_addr function for sorting ala memcmp.
