[Hyper-V][SAUCE] hv_sock for 4.10

[Joshua R. Poulson]

Please include the latest version of Hyper-V Sockets (hv_sock) for the 4.10 kernel against the Azure kernel. This is SAUCE as this has not yet been submitted or accepted upstream in this form.

A few comments and questions:

1. Should we include the hv_sock module as built-in or keep it as a module?

2. It's better to try to reserve in upstream the address family number (AF_HYPERV) to avoid conflicts with future rebases and problems with userspace.

3. It seems that net/core/sock.c also needs to be updated with AF_HYPERV. I can include those changes on the patch that I will submit to our mailing list. But I'd like to have that patch reviewed but Microsoft.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-xenial' to 'verification-done-xenial'. If the problem still exists, change the tag 'verification-needed-xenial' to 'verification-failed-xenial'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
