            When creating a socket to listen for new connections, the new code always creates and IPv6 socket, and requests that IPv4 connections be handled on that socket.

            Unfortuantely, this doesn't work if IPv6 support isn't available -  -EAFNOSUPPORT is returned when creating the socket.  So I'll have to detect that and try.

             

            Please test https://review.whamcloud.com/41791 and report if that fixes the problem.
