Subject: [net-next PATCH] test: hsr: Extend the hsr_redbox.sh to have more SAN devices connected
After this change the single SAN device (ns3eth1) is now replaced with
two SAN devices - respectively ns4eth1 and ns5eth1.
It is possible to extend this script to have more SAN devices connected
by adding them to ns3br1 bridge.
