Merge "Stop reducing RA advertised ipv6 mtu by 16 - not needed." am: 01dab1a0

            final String upstreamIface = v6only.getInterfaceName();

            params = new RaParams();

            // 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)

            // see RouterAdvertisementDaemon.java putMtu()

            params.mtu = mUsingBpfOffload ? v6only.getMtu() - 16 : v6only.getMtu();

            params.mtu = v6only.getMtu();

            params.hasDefaultRoute = v6only.hasIpv6DefaultRoute();

            if (params.hasDefaultRoute) params.hopLimit = getHopLimit(upstreamIface, ttlAdjustment);
