+ net: split eth_mac_addr for better error handling
+
+ When we set mac address, software mac address in system and hardware mac
+ address all need to be updated. Current eth_mac_addr() doesn't allow
+ callers to implement error handling nicely.
+
+ This patch split eth_mac_addr() to prepare part and real commit part,
+ then we can prepare first, and try to change hardware address, then do
+ the real commit if hardware address is set successfully.
