[clue] EL-6 Ethernet port bonding

Mon Jul 15 15:15:05 MDT 2013

I attempted both adding the options to my modprobe.d/bonding.conf and
moving everything to /etc/modprobe.conf but both failed the same
way. /etc/modprobe.conf is deprecated and the Red Hat docs say to not put
the options in the bonding.conf.

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