Merge "Stop reducing RA advertised ipv6 mtu by 16 - not needed." into rvc-dev am: 14756a8c

            // When BPF offload is enabled, we advertise an mtu lower by 16, which is the closest

            // multiple of 8 >= 14, the ethernet header size. This makes kernel ebpf tethering

            // offload happy. This hack should be reverted once we have the kernel fixed up.

            // Note: this will automatically clamp to at least 1280 (ipv6 minimum mtu)
