Real-world use of Linux multipath TCP

LWN looked at the Linux multipath TCP implementation back in 2013. That code remains out of tree, but it now seems that it is being used in some Samsung phones in Korea. "This service enables smartphone users to reach bandwidth of up to 1 Gbps on existing smartphones. This is probably the fastest commercially deployed mobile network. They achieve this high bandwidth by combining both fast LTE (with carrier aggregation) and fast WiFi networks on Multipath TCP enabled smartphones." (Thanks to Oliver Bonaventure).
