Install nftables and move the default conifuration in ebtables.filter.cfg to nftables.conf.

[Minkang-Tsai]

What I did
Replace the ebtables with nftables.

Why I did it
Nftables can configure the more detailed rule to filter packets.

How I verified it
Execute "nft list ruleset bridge" command

table bridge filter {
        chain INPUT {
                type filter hook input priority filter; policy accept;
        }

        chain FORWARD {
                type filter hook forward priority filter; policy accept;
                ether daddr 01:80:c2:00:00:00 counter packets 0 bytes 0 drop
                ether type arp counter packets 0 bytes 0 drop
                ether type vlan vlan type 0x0806  counter packets 0 bytes 0 drop
                ether daddr & 01:00:00:00:00:00 == 01:00:00:00:00:00 counter packets 0 bytes 0 drop
        }

        chain OUTPUT {
                type filter hook output priority filter; policy accept;
        }
}
