(BI remember that application increments its pointer manually by
(Bsizeof(struct sockaddr_in6) - sizeof(struct sockaddr) bytes,
(Bbut it is not good for Linux because we don't know the actual size of
(Bsockaddr_in6 structure returned from kernel (and would vary if kernel
(Bsupports sin6_scope_id) --- please remember, we don't have sa_len
(Bmember in sockaddr{}. If you have any idea on this, please tell us.

(BFYI:
(B sin6_scope_id patch (done by me) is now available,
(B but I don't know when it goes into the main source tree...
(B After that, we could have IPv6 support for SIOCGIFCONF (because old
(B kernels won't return sockaddr_in6 and applications would not be
(B confused by difference of sizes).
