    Description

      We should fall back to IPv4 if QHostAddress::Any is used when IPv6 is disabled on the system.
      Currently QNativeSocketEnginePrivate::createNewSocket fails due to EPROTONOSUPPORT

      Affects people who built a kernel without IPv6 in order to save memory.
      Most binary distributions ship a kernel with IPv4 and IPv6 both enabled.

      Reject this issue if we don't want to support such kernels.
