Use eth_hw_addr_random() instead of calling random_ether_addr() to set addr_assign_type correctly to NET_ADDR_RANDOM. Reset the state to NET_ADDR_PERM as soon as the MAC get changed via .ndo_set_mac_address. v2: adapt to renamed eth_hw_addr_random() Signed-off-by: Danny Kukawka <redacted> --- drivers/net/dummy.c | 3 ++- drivers/net/ethernet/broadcom/bnx2x/bnx2x_cmn.c | 1 + drivers/net/ethernet/broadcom/bnx2x/bnx2x_main.c | 2 +- drivers/net/ethernet/calxeda/xgmac.c | 3 ++- drivers/net/ethernet/marvell/pxa168_eth.c | 3 ++- drivers/net/ethernet/micrel/ks8842.c | 3 ++- drivers/net/ethernet/micrel/ks8851.c | 3 ++- drivers/net/ethernet/micrel/ks8851_mll.c | 1 + drivers/net/ethernet/microchip/enc28j60.c | 3 ++- drivers/net/ethernet/nvidia/forcedeth.c | 3 ++- drivers/net/ethernet/smsc/smsc911x.c | 3 ++- drivers/net/ethernet/tile/tilepro.c | 3 ++- drivers/net/macvlan.c | 3 ++- drivers/net/team/team.c | 3 ++- net/bridge/br_device.c | 3 ++- net/openvswitch/vport-internal_dev.c | 3 ++- 16 files changed, 29 insertions(+), 14 deletions(-)
