[clue] EL-6 Ethernet port bonding

[adam bultman]

Your modprobe.conf, or modprobe.d stuff, is missing the bonding info.

I'm not sure how version 6 does it, but on Centos5.9, I have:

alias bond0 bonding
options bond0 mode=4 miimon=100 downdelay=200


in my /etc/modprobe.conf file.  You might need to put it in
/etc/modprobe.d/bonding or something, though.
