"""ACL IRB Test Case HLD:

**config**
    - L2 MAC learning enabled in l2bd
    - 2 routed interfaces untagged, bvi (Bridge Virtual Interface)
    - 2 bridged interfaces in l2bd with bvi

**test**
    - sending ip4 eth pkts between routed interfaces
        - 2 routed interfaces
        - 2 bridged interfaces

    - 64B, 512B, 1518B, 9200B (ether_size)

    - burst of pkts per interface
        - 257pkts per burst
        - routed pkts hitting different FIB entries
        - bridged pkts hitting different MAC entries

**verify**
    - all packets received correctly
