The effect of this was, for clients mounted via inet6 addresses, that the DRC cache would never have a hit in the server. It also broke NFSv4 callbacks when an inet6 address was the only one available in the client. This patch fixes the above, plus deletes opt_inet6.h from a couple of files it is not needed for. END
