Who actually processes these router advertisements: the rtsold daemon or the kernel itself? Is this passage: 8.1.1.4. Plug and Play Most of the IPv6 stateless address autoconfiguration is implemented in the kernel. Neighbor Discovery functions are implemented in the kernel as a whole. Router Advertisement (RA) input for hosts is implemented in the kernel. Router Solicitation (RS) output for endhosts, RS input for routers, and RA output for routers are implemented in the userland. still correct?
