Hyper-V vethernet don't work with 10Gb

I have created a vethernet in Hyper-V, I have 2 RJ45 both Intel(R) Ethernet Connection X722 for 10GBASE-T, but the first RJ45 connected 1 Gb port and the second RG45 connected 10Gb port (physical switch 10Gb). If I connect vEthernet with first RJ45 Hyper-V work and it serf into internet else Hyper-v don't serf into internet.
