Yes, right. SIOCGIFFLAGS is just faked to handle the default case. See fhandler_socket::ioctl(), it doesn't even call get_ifconf in case of SIOCGIFFLAGS. The code is older than the advent of get_2k_ifconf, AFAIR. Hmm, it shouldn't be too hard to support SIOCGIFFLAGS more or less correctly starting with Windows 2000. I put this on my TODO list.
