From 37905ae131a728d90515bb9258f195edb6c5d5a2 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Tue, 21 Aug 2012 16:39:04 +0800 Subject: [PATCH] Staging: rtl8192u: using random_ether_addr() to generate random MAC Using random_ether_addr() to generate a random Ethernet address (MAC) that is not multicast and has the local assigned bit set. Not need to duplicating its implementation. spatch with a semantic match is used to found this problem.
