The issue got introduced in a cleanup by Manjunath Hadli in commit 826e99136e2bce61f3f6572e32d7aa724c116e6d. The eth_getenv_enetaddr_by_index method will validate the MAC addr and if none is set in the environment 0 will be returned. Set the MAC from the eeprom if no valid address is found in environment. --- arch/arm/cpu/arm926ejs/davinci/misc.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-)
