From c5d6a966762eb5bac5960235461fd6893aaa8498 Mon Sep 17 00:00:00 2001 From: Jiri Pirko Date: Wed, 14 Nov 2012 02:51:04 +0000 Subject: net: correct check in dev_addr_del() [ Upstream commit a652208e0b52c190e57f2a075ffb5e897fe31c3b ] Check (ha->addr == dev->dev_addr) is always true because dev_addr_init() sets this. Correct the check to behave properly on addr removal. Signed-off-by: Jiri Pirko Signed-off-by: David S.
