   4 Subject: [PATCH] net/i40e: disable source pruning on pf
   5
   6 VRRP advertisement packets are dropped on X710 and XL710 devices
   7 because when a MAC address is added to a device, packets originating
   8 from that MAC address are dropped. We disable source pruning to work
   9 around that issue.
