Adapt adi ethernet driver to changes in bfin_get_ether_addr() from arch/blackfin. bfin_get_ether_addr() returns now a state. Set a random mac address via new eth_hw_addr_random() in case the return value is not 0. Reset the state to NET_ADDR_PERM as soon as the MAC get changed via .ndo_set_mac_address. v2: change the logic to reduce unneeded checks Signed-off-by: Danny Kukawka <redacted> --- drivers/net/ethernet/adi/bfin_mac.c | 15 +++++++++------ drivers/net/ethernet/adi/bfin_mac.h | 2 +- 2 files changed, 10 insertions(+), 7 deletions(-)
