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 <danny.kukawka@bisect.de> --- net/ethernet/eth.c | 2 ++ 1 files changed, 2 insertions(+), 0 deletions(-)
