This is not correct. A 40Gb link does not limit a single transfer to 10G. For example, on FreeBSD all common bandwidth benchmarks reach 40GbE line rate with a single TCP connection at mtu 1500. If a single transfer were limited to 10G you'd need 4 connections to get there. The physical signalling is over four lanes so it's easy to split a 40G link into four separate 10G links. But when running as a 40GbE (this is the usual case) the hardware will combine all the lanes into a single 40G data stream, and you get to use all of the bandwidth.
