Find MAC addresses in /proc or somewhere despite bonding device?
Solution 1:
I'm still searching for a more "official" explanation, but according to this blog, the file /proc/net/bonding/${bonding name} will provide the actual mac address for each NIC in the bond (eth0, eth1, etc..), so that might be more useful.
Hope this will help!
Solution 2:
On RHEL/CentOS 6:
# ethtool -P <if>
Permanent address: 00:11:22:33:44:55
