Hi there, I'm trying to understand the way IPv6 routing is implemented in the linux kernel (2.4.27) I'm seeing many #ifdef CONFIG_IPV6_SUBTREES, but cannot see where this tag is defined. Could anyone tell me what is used for? thanks. /Seb. -- Kernelnewbies: Help each other learn about the Linux kernel. Archive: http://mail.nl.linux.org/kernelnewbies/ FAQ: http://kernelnewbies.org/faq/
