Important addition:

The mac of the 2nd nic added, is the same mac, but yet differ in case sensitivity! 
If the exact mac is given to the 2nd nic, including case sensitivity - the nic add fails (that this mac already exists...) 

For example if the mac is:
00:1a:4a:23:a0:db, adding a second nic with mac 00:1a:4a:23:a0:db will fail, but adding a 2nd nic with mac 00:1A:4A:23:A0:DB will succeed.
