The mc_local_lb switch disables multicast loopback traffic for mlx5en(4) without SR-IOV enabled only. I've Mellanox ConnectX-4 Lx with enabled SR-IOV and there is always multica= st loopback. Ex, CARP traffic always loops back when SR-IOV enabled. --=20 You are receiving this mail because: You are the assignee for the bug.=
