According to e.g. comment in it seems that nftables have no implemented syntax for source and destination ipv4 address in arp tables right now.

So solution/workaround for this issue for us would be to switch to ebtables-legacy on Ubuntu Focal, at least for now.

    Use ebtables-legacy on Ubuntu Focal

    On Ubuntu 20.04 there is by default ebtables-nft used. The problem with
    that is that nftables don't supports syntax for source and destination
    ipv4 address in arp tables right now.
    So to workaround/fix this problem at least in our gate jobs we have to
    switch to ebtables-legacy for now.
    And that's exactly what this patch is doing.
