In fact, > addrconf_dev_config() will not add link local address because this function > filters interfaces by type. If the link local address is added manually, the > route to the link local prefix will be automatically added by > addrconf_add_linklocal(). > Note also, that this route is not deleted when the address is removed. > > After looking at the code, it seems that addrconf_add_lroute() is redundant with > addrconf_add_linklocal(), because this function will add the link local route > when the link local address is configured. > > Signed-off-by: Nicolas Dichtel <nicolas.dichtel@...nd.com> Applied. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
