Finally we added support for ip bonding in tfm. How a config will look like?
In /etc/sysconfig/network-devices directory create a directory named ifconfig.bond0 with the following content:
ONBOOT=yes
ONHOPLUG=yes
SERVICE=ipv4-bonding
IP=192.168.1.1
PREFIX=24
BROADCAST=192.168.1.255
CHECK_LINK=no
BONDING_SLAVES="eth1 eth2"
BONDING_MODE=4
BONDING_MII_DELAY=100
