network bonding on slackware 14.2

perhaps a first sloppy attempt I made to make bonding work in 14.2, based on this info

https://docs.slackware.com/howtos:misc:network_interace_bonding

inside /etc/rc.d/rc.M add (before rc.local section):

if [ -x /etc/rc.d/rc.bond ]; then
  . /etc/rc.d/rc.bond
fi

/etc/rc.d/rc.bond :

modprobe bonding

ip addr add 192.168.111.3/24 dev bond0
ip link set bond0 up


ip link set eth0 master bond0
ip link set eth1 master bond0

ifconfig eth0 up
ifconfig eth1 up

ip route add default via 192.168.111.13 dev bond0

chmod +x rc.bond and reboot
