The patch already uses cifs_convert_address which handles IPv4 or IPv6
addresses just fine. I don't think it would be that difficult to
optionally store a v4 or v6 address to bind socket.

You'll also need to think about what this means for ip address
selection in the mount helper. It'll need to be modified to make sure
that the address families between the two match. What happens if
someone specifies and IPv4 bindaddr, and the host in the UNC resolves
to an IPv6 address?
