From 8feedbb4a710784d2858acba5c90e903e93e36eb Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Tue, 8 May 2012 18:56:57 +0000 Subject: [PATCH] dsa: Convert compare_ether_addr to ether_addr_equal Use the new bool function ether_addr_equal to add some clarity and reduce the likelihood for misuse of compare_ether_addr for sorting.
