From c8585bd89e2e3c87eab6ca711e09b3af20fd469b Mon Sep 17 00:00:00 2001 From: Danny Kukawka Date: Thu, 9 Feb 2012 09:48:53 +0000 Subject: [PATCH] eth: reset addr_assign_type if eth_mac_addr() called If eth_mac_addr() get called, usually if SIOCSIFHWADDR was used to change the MAC of a ethernet device, reset the addr_assign_type to NET_ADDR_PERM if the state was NET_ADDR_RANDOM before. Reset the state since the MAC is no longer random at least not from the kernel side. v2: changed to bitops, removed if() Signed-off-by: Danny Kukawka Signed-off-by: David S.
