"""Custom LACP topology for LACP Module testing

1.Two hosts(H1,H2) two interface each  connected with Switch(S1)

Execute Custom topology:
sudo mn  --custom LACP_custom1.py --switch ovsk,protocols=OpenFlow13 --topo=lacp

Note:
 1.remoteController IP will be replaced in LACP_custom1.py using sed command during the robot execution
 2.bonding.conf will be copied the mininet server under /etc/modprobe.d
 3.h1-bonding.sh h2-bonding.sh will be executed in respective h1,h2 host console
