"The first interface to be enslaved." How do I know which one that is to be? How do I elect one MAC over another?

haven't done much bonding in full linux systems- mostly just embedded or dedicated network kit.

but!

https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Deployment_Guide/s2-networkscripts-interfaces-chan.html

per 10.2.4.2., "The MAC address of the bond will be taken from the first interface to be enslaved. It can also be specified using the HWADDR directive if required."

this would be in /etc/sysconfig/network-scripts/ifcfg-<your bond iface name> (see example 10.1. on that page)
