test: hsr: Extend the hsr_redbox.sh to have more SAN devices connected
Browse files Browse the repository at this point in the history 
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.
