From 6a214fd4142d585ef2226e8ef6bc29a15403506f Mon Sep 17 00:00:00 2001 From: Danny Kukawka Date: Fri, 17 Feb 2012 05:43:30 +0000 Subject: [PATCH] atheros eth: set addr_assign_type if random_ether_addr() used Set addr_assign_type correctly to NET_ADDR_RANDOM in case a random MAC address was generated and assigned to the netdevice. Fix error handling in atl1c_probe(). If atl1c_read_mac_addr() couldn't get the hw mac address, and a random mac address get set return the error code. Don't go to err_eeprom in atl1c_probe(), use the generated MAC address in this case. Reset the state to NET_ADDR_PERM as soon as the MAC get changed via .ndo_set_mac_address. v2: use bitops Signed-off-by: Danny Kukawka Signed-off-by: David S.
