Major When arp_proxy is configured at a LSP with the following values
arp_proxy="0a:58:a9:fe:01:01 169.254.1.1 fe80::1 10.244.0.0/16"
And an GARP with operation=1 arrive at a LSP withing the logical switch owning that the arp_proxy LSP ovn is answering back the GARP instead of broadcasting it to all the LSP ports.
