brist v1.1

Changes

• Improved documentation: README now details how to run on HW
• Lots of option flags added to tweak the behavior of brist
• Support for randomizing the port mapping, including saving the mapping so it can be reused to repeat the exact same test
• Support for advanced filtering of which tests to run
• Add support for single-stepping, brist.sh -S
• Add online brist.sh -h to show usage
• New tests:
  • basic_learning_station_move
  • basic_flags_flooding
  • vlan_transparency
  • vlan_filtering
  • vlan_ivl
  • basic_locked_port
  • locked_port_vlan
  • locked_port_spoofing
  • locked_port_mac_auth
  • lag_basic_connectivity
  • lag_add_link
  • lag_remove_link

Fixes

• Ensure brist.sh is installed with executable perms
• Only use zero exit code when no tests failed
• Fix port list, no port $b5 exists, only $b4
• Flush addresses and routes from interfaces between tests. Otherwise lingering addresses interfere with new ones
• Fix multi_learning_ports with >3 pairs
